All lanes are 60’, from the foul line to the arrows it’s approximately 15’ so we have 1/4 of the lane from foul to arrows and 3/4 from arrows to pins. That means that when using a certain arrows the proportion from lay down point to the pins is 3:1. If we lay the ball down at 20 and use the middle a...

Without looking at your hand it is very difficult to recommend a fit. There are various schools of thought so if you go to three different shops you will get three different opinions. Are those cut spans? If they are full spans you definitely have a small hand and 1/16 reverse may be too much revers...

Just my 2 cents, my daughter is also a lefty and has similar specs but about 100 less rpms so much more speed dominant than you. She has 2 strong balls: the original Envy 50 x 3 3/8 x 25 usually at 1000 and it is great on short and medium IBF patterns. From that she will step down to her benchmark w...

Tundra Fire with a larger pin to pap and VAL angle

Ball’s going around the body and you’re sliding way left of your line. For reference if you’re bowling up 10 your slide should be 15-16, thats second arrow aiming at the 6 pin. Second arrow aiming at the 10 pin then slide 16-17… Ball should replace your right leg on the way back and then again on th...

For a house shot you really don’t need that many balls. Low revs I am asuming you mean 200-250 rpms and 12-14 mph I am asuming you mean at the monitor so that’s about 15-17 off the hand which is slow to moderate speed. You could actually be considered matched to slightly rev dominant if my revs gues...

Lane’s 60’, arrows are around 15’ down If we are going straight up 10, ball laydown is 10, arrows is 10 and ball rolls in the direction of the 6 pin (precisely the left base corner of the pin which is the 10 board). Launch angle is 0* If we use the same board at the arrows as a pivot point (constant...

We need to know if you are speed dominant, matched or rev dominant. Knowing your axis tilt will also be very helpful. Being able to roll urethane at your spares will allow you 5 reactives in your 6 ball arsenal. Otherwise then a purple hammer and your polyester will allow you 4 reactives. Knowing yo...

Variations in manufacturing, those small variations will not affect ball motion nor will you feel them.

1) Lower that axis rotation to at least 45*, should feel like you’re rolling it straight. Less is more, less hand and more speed is better. Play first arrow and roll it in the direction of the 10 pin, more towards the right belly of the pin. 2) Drill a Purple Hammer 45 x 4.5 x 30, 500 surface to get...

One thing that is often overlooked among bowlers that are returning after a long hiatus is to reevaluate your fit. Spans today is way more relaxed than what they were 30 years ago because ball technology now requires us to release into the lane instead of hitting up and making it hook. Also your han...

Nevermind, tried method B “ lay the hand without stretching the web, no wrinkles, full contact of web and index finger yet still very relaxed.” feels great for me, even with forward pitches. After trying two handed for 5 years and never really getting as good as I want to get, went back to one hande...

Hello, to those PSO and coaches using the instructions in the Wiki (MoRich Fitting Instructions) for a base fit, what thumb web tension are you using? Guide calls for “no” web tension and in my opinion this is very open to interpretation… For example, one could just lay the hand and the thumb web co...

Walter, your fit is probably more in line with what most use today which is what I was taught at Kegel when I took my pro shop class recently. More reverse in fingers with a minimum of 3/8 reverse in fingers and 0 forward in thumb for a 4.5” full span with bottom edge of insert/hole coinciding with ...

Best to get a mild reactive like a Twist or a Surge and drill conventional with 3/4 to 1” reverse, no inserts. Many new no thumb bowlers have negative tilt and this is caused by a late release and the thumb going clockwise (for right handers) at release. Relaxed pitches and no inserts teaches to rel...

I do realize this is an old post, sorry for the late reply I am going to start being more active on the forum once again. I always recommend proper coaching as realease issues are best worked on at the lanes and many factors come into play. Most often than not the release is not the issue but merely...

Yes! That’s definitely a good idea and golf is a great analogy! https://youtu.be/XwViMKq8PqI If you have a chance to book a lesson with Alex Gurkov or Del Warren that would be the best decision, very few coaches know how to teach the style. Alex is in Las Vegas and often goes to Florida, Del is in F...

If you are a Bronze level coach or equivalent I would strongly suggest Kegel’s KCMP1. They have it online every now and then, of course in person is best

No, just pin to pap and VAL angle. I like to use plenty of surface on urethane, they work very well when the gutter plays in sport shots.

Layouts and PAP are not going to be very important when changing to no thumb one handed. My suggestion as a coach who coaches plenty of two handed youth and a fairly good one handed no thumb adult, would be to go down 1 or 2 lbs and work on technique. Put the pin 1-1.5” above the RF on a mild symm l...
