I listened in on that Webinar, and found it to be very useful. I have struggled to get my over-sized arsenal pared down. I dug out all of the bowling balls I have, and placed them in a spreadsheet (attached) that mimics their template. It quickly "showed me the way". I know first-hand that Del likes...

I am confused about the proper direction and line of play. And, there seems to me to be two schools of thought. On the one hand, the slide foot stays parallel to the lanes, the ball-side foot is slightly behind the slide foot, and the body opens up to accommodate the desired line of play as you appr...

Check out the #MoMonday video on this very subject.

Mav, I may owe the reading community an apology. Ron's Layout #2 with pin-in-finger may not be Mo's Layout-C. Ron has the Blueprint snapshot of Layout #2 as 80 x 4.5 x 40, and that appears to be the values entered into Blueprint. When I model it and draw it out on a bowling ball, it does not put the...

This is kind of my “book report” on the presentation – LOL! Ron Hickland, Jr. is much more laid back in this YouTube video presentation of an introduction to symmetric layouts for us average bowlers. Usually, he is very animated and rapid talking. This presentation talks about bowler specs, lane con...

I assume this update is a result of the USBC rule change regarding balance holes. Section 4 - Drilling Patterns and Layouts of the previous manual gave examples of layouts for symmetrically-cored balls. Even that manual had an illustration error on page 4-22. The example was for Low Pin - No Balance...

Dark Horse, the post is titled "bailing out proprietors", not local associations - just saying. And, I agree that having a dedicated USBC inspection crew should be more expensive, and take longer to complete overall (not knowing how many teams will exist) when you consider salaries, benefits, and tr...

Stacy, a follow-up on my plugged SYM balls. Over Thanksgiving, I had the opportunity to spin up two of my SYM balls that have been plugged. These balls have the deeper thumb holes. What I noticed on both of these balls is that they will quickly gravitate toward the plugged P3 balance hole location a...

Hmmm, some lookers but no takers... I read some older information that the PSA can move in odd ways with some core designs. Sometimes the mass moves around in funky ways. These balls characteristically are touchy, and don't do what you drill them to. This describes my Rave. Some known examples was t...

I have a Radical Rave that I have never really liked. It has always been hit or miss for me. It has been re-drilled for span and pitches, but has always had a nn x 4 x 40 layout on it with a P3 balance hole. When I re-drilled it for comfort the last time, I plugged the balance hole. I have rolled it...

I recently got an email from the USBC Bowling Academy inviting me to download a document called “5 Ways to Increase Your Bowling Average”. It is a basic “care-and-feeding” of your bowling equipment type of article – commonsense stuff but good. There are various hyperlinks embedded in the document to...

Stacy, I am gonna have to find that video you reference, and check it out. Eric, You would be surprised at the number of drilled balls in my area where the Pin is obviously too close to the finger holes. I see it in the pros but they don't care as they don't keep a bowling ball very long. And, I agr...

I am gonna apologize up-front for the length of this post. OK. I am confused. I have been viewing the #MoMonday videos on various topics, and reading the mail related to those topics. With changing USBC rules, market pressures, and technology changes, Mo's position on layouts is changing – becoming ...

Thanks to Mo and MegaMav for the PDF of the presentation. Dean, I am going out on a limb here and say that part of the confusion and "discrepancies" may be due to being in a transition period. Here are my assumptions and I will wait until the dust settles on this stuff: 1. The 9 simplified layouts r...

KYBOB, This is how I interpret what Mo said (assuming he hasn't altered his position since the video was produced): In my example, I will use a 1-1/2 inch slug (to remove as much material as possible) and then drill the thumb hole 1-1/4 inch for a thumb insert. So, I would drill the first hole 1-1/2...

Wow, Kyle, thanks so much!
It seems like the more I try to keep up the further behind I get! LOL!

Really? I always liked making the hole a tad smaller at the bottom of the insert length to about 4 inches to give me a "shelf" to bottom out the insert (keeping it from going too deep when being installed). I have a longer thumb so I always need/like to have the thumb hole deeper than the insert len...

Stacy,

That's probably true if you could drill the thumb holes deeper. But it seems that is illegal, so this layout remains suspect in my mind. TDK

Thanks! I never get to attend Mo's seminars. My take-away from all of this is: 1. Pro Shops only need to consider these 9 layouts (4+5) - for the average bowler. 2. Pin-Down layouts have a place, but never on SYM balls. 3. The Drilling Angle does not matter on SYM balls. 4. Urethane is frowned upon ...

I want to preface this post by saying that I understand ideas and suggestions can change with new information, more experiences, and advancing bowling technology. Having said that, I was reviewing the most recent MoMonday video where Mo answers a question about Pin-to-PAP distances. Mo talked about ...
