IT vs Switch Grip

Post by fufu » February 10th, 2019, 4:11 am

The shop I work in uses the Switch Grip. I really have not been that satisfied with the product. Idk if I simply got a bad batch of inner sleeves, but they wouldn't stay locked in and fall out in the machines or under the ball return. Myself, and my counterpart, are looking at whether or not we should transition to the IT system. We both have limited experience with that system. Aside from the extra number of steps and pieces, which do you use/prefer and why?

I use Switchgrips and I have a couple of balls/thumbs that just don't stay locked in like you describe.
I wrap a small ponytail rubberband around the base/locking tabs on the inner. This tightens up the fit nicely. They are about a one time use sometimes I can take it out and use it again without the rubberband breaking. So at about $1 for 100 of them I have plenty but I try to not take out my thumb from my strike ball to use in my spare ball. It is my spare ball that I have the loose fit issue with most all my thumbs. My yellow thumb is a problem in most all of my balls so it always has a rubberband on it in awaiting use. My black thumb is also an issue but only in a couple of balls. I am sure as I get more wear I will be using rubberbands on more of them.

I think there is more room for pitch adjustments with the Switchgrip.

Drilling the thumb deeper is not an option with the IT.

I have not tried the IT so I can't really comment any more about it.

I install Vise IT on a regular basis.
The parts are cheap.
It's easy to install and repair.
In my area, the IT system is much more common than Switch-grip.

It is probably less durable than the Ultimate and Turbo systems. I repair 2-3 IT systems per month, usually due to broken Ball-IT's or Slug-IT's.
You'll probably have to buy the Ferarri Ball Jig in order to drill a hole in the slug-IT.
Alignment and fitting to the hole for the Collar is hyper-critical to a good installation.

FYI, the IT Collars have a very subtle taper, and they go into the ball best with the narrow side down. You can find this subtle taper by trying both sides of the collar; the side that slips into the hole easiest is the narrow side.

I’ve been using the SG for years. I had one come out in the under the lanes while the ball was in transit back to the ball lift while bowling in the NY State tournament. That wa sthe last time that ever happened. Read on:

If you have one that comes out too easily, simply lay it on your bench or other table and smack it a few times with something with a corner on it like a file or a bevel knife. Doing so will leave small dents in the outside of the inner sleeve. Test the fit. The little dents should provide enough interference friction to stop it from coming loose on its own. Do this a little at a time testing after each smack because the effect is powerful ang you don’t want to overdo it.

Where on the outside of the inner are you smacking it?
Towards the bottom, top, middle or on the edge of the bottom corner?

I smack it (make small dents) halfway up the outside of the inner sleeve/slug.

I have used small pieces of scotch tape on the outside of one of my inners to tighten it up.
I will give your method a try. Thank you.

Mo uses a piece of black tape on the outside of the SG sleeve to tighten them up if need be. He says that's the only use for black tape. lol.

+1 for scotch tape. I have 5 balls that have them. When the slug is too loose on the hole, I put one stripe of scotch tape almost all the way from bottom to the surface. Then test the slug. If it is still loose, I'll add another. One of my balls have them on 3 sides. My SG was originally drilled at the PSO who seemed to have a little bit different size drilling bit. Then the inner sleeve was slightly sanded and now it is always a bit loose fit when done at the current PSO.

I have utilized and drilled SG and IT. I feel like SG is a little more rugged but a little less polished. For me IT is more like a Ferrari and just has such a better look when finished (mine look just like a glued permanent slug), but maybe a little bit more delicate. In my experience, IT is faster for the pro shop. I prefer gluing the sleeve for the IT system to the top of my thumb slugs, so that I don’t have to glue a sleeve to every single ball I drill. IT can be a pain in the butt if something goes wrong with the drilling or install. You pretty much have to use plug and start over the next day. You have a little more forgiveness with SG in my opinion. I haven’t had a Ball IT or Slug IT fail yet in my limited experience. I believe you lower the risk of failure by ensuring the top of the slug doesn’t stick up above the ball. Working the slugs on IT can feel a little more tedious than SG slugs. You have to be a little more careful making IT slugs flush because you don’t want to scratch the ball. With SG slugs the thicker outter sleeve gives you a little protection from scratching the ball. Hope this isn’t too much info. Oh ya... I prefer IT because it feels more precise.

Cecil at Vise taught me a quickie method for fixing a failed Ball-IT.
Drill out the Ball-IT with 1.125" drill, 1" deep. Install a VISE 1.125" slug in the hole and drill out the excess with the IT drill bit. works like charm and only takes about 10 minutes.

I'm using Turbo switch grip and I'm ready to go back to vise. My switch grips never fit the same between balls.. some are super hard to turn and some don't even click at all and come out super easy.

I've lost one in the pit. Before I had separate thumbs for my spar ball I had to have my thumb redone 3 times because it eventually got too loose and wouldn't stay locked at all.

I use the tape trick on the balls that are loose. I guess it does the job.. Still should be a better product.

I've only used Switch Grips at Demo Days, they were whatever I guess. I have the IT in all of my balls, and have nothing but good things to say about this system, and can highly recommend it.

I have switch grips in several balls. No real issues with them, but it's the only experience I have with swap-able grips. I do know it's really nice to have a consistent fit when I switch balls.

I have switch grips. 1st four that were that were drilled the tabs on them broke. Of course at a tourney in another city and no other house uses them.

After close examination I determined that the pso drilled down too deep and got into the inner sleeve.

He replaced them at no cost and was more careful drilling out the new inner sleeves.

Have not broke one in a year since. Up to 3 nights a week not including tourneys.
