Inverted Track, we are talking about a PAP location that has a down component to it, the track is closer to the fingers and further away from the thumb, correct?

It is actually really simple. Lay the ball out 45-4-35 then use the 4.5 over .5 up PAP measurement to find the grip center.
I don't see where the confusion is.

I hear you with knee issues! Just getting back after knee replacement. Dropping weight will always result in more deflection just because you have less weight hitting the same amount of weight. More speed will offset some of that. Not "always" true. On what I consider the perfect strike, the ball h...

There are some very good offerings out there for 12 and 13 pound equipment. I currently utilize 13# equipment with proper layouts for my release. Proper layouts are the key to being able to maximize the potential of lighter equipment. Check out this link... http://forum.bowlingchat.net/viewtopic.php...

Certainly looks like a decent replacement for when mine gives up its ghost.

Thanks again for satisfying my curiosity.

Thanks Glenn, it looks more robust than the NuBall.

I understand not wanting to tear apart something brand new, but I am that sort of person that can't resist opening something up to see how it works and don't hesitate at all when something needs to be fixed. Sure the surface cools a little bit but the core temp doesn't change in the minute or two it...

The Pyramid Phoenix Revivor appears to be a pretty good product. I jumped on the NuBall bandwagon when they first came out. It does a fine job and will keep using it until it wears out. I have had to re-lubricate the bushings in the fan and will need to do so on a regular basis to keep it running. W...

I have a theory... A reactive bowling ball is like a sponge. Dry sponges get hard, brittle and shrink. When this happens to a bowling ball and the surface tension can become too much, the result is cracking. I have only had 2 balls crack and both of them were clean, free of oil and been in storage f...

If by optimum you are referring the maximum Hook potential you might be on to something. But if optimum means Strike potential, I am not so sure you could pick an optimum angle of rotation based on speed and revs alone. Thinking that the length of the oil pattern would need to be factored in as well...

Ok it's not "Totally" disappointing. From a bowling stand point yes, but from a survival standpoint it is not even close. I am surprised the the Olympic Committee hasn't yet followed suit. Sports whether it be professional, college or recreational leagues have all cancelled. The Olympics are by far ...

Here in Michigan all restaurants, bars, and places of recreation have been shut down by decree of the Governor. Basically we are under Marshal Law.
I had just hit a stride with my bowling game just in time for the tournament season.
This is totally disappointing.

The good thing, if there can be any good with an injury, the upper bicep has 2 tendons and you can still function with only one attached. Both my wife and a cousin had complete tears of one tendon and both are still bowling effectively. I bowl with another guy that has had lots of trouble with his s...

Your speed off the hand is closer to 19 mph. This makes you slightly speed dominant until you factor in your low tilt making you slightly rev dominant. Tweener as you already described. Sweetspot 100* totals, 2:1 Ratio Asymmetrical Layouts Totally Strong .......... 55-4.5-25 Midlane ...................

Welcome to BowlingChat

Before I give you layouts I need to know how your speed is measured.

What balls and layouts are you currently using?

The Billy Hardwick rubber ball.
Haven't seen any posts from Nord as of late, that was one of his favorite balls,

Not $200, $126.95 Better than list price back in the day. I paid $135 for my Original Back Hammer. https://www.ebay.com/i/121786709530?chn=ps&var=420778048108&norover=1&mkevt=1&mkrid=711-117182-37290-0&mkcid=2&itemid=420778048108_121786709530&targetid=877051577709&device=c&mktype=pla&googleloc=90175...

I can't seem to find the old hammer black that I used to throw as a kid and the new hammer urethane seems to be designed for stronger hook. Probably end up going with a pitch black. If you can get your hands on one of Hammer's Black Urethane I would. It is essentially a replica of the original. Sur...

We already know 3000 is liked by Awinnie54 and I am guessing there is a compromise with the surface to try to keep the ball playable in the 3rd game.
I would have enough surface on it to dictate a ball change after the first game. 1000 grit is where I would start.

I currently use a Hammer Black Widow / Black Gold ball at 15lbs. I am wanting to drop to 14lbs due to some shoulder issues and would love to have my same Hammer Black Widow Black / Gold ball. However, with Hammer being bought out by Ebonite?, I can no longer find this ball. It is not that Ebonite B...
