If you genuinely have 0 tilt, high ratios are not recommended.
Not if you're interested in scoring consistently at least.

what shapes should I go for and how many balls will it take? I have a lot of aggressive stuff with smooth shapes right now. I need some hockey stick shapes of different angles or sharpness of the shape (skid/flip strong to weaker)
110* drilling angle is outside the guidelines for the Dual Angle Method and even so it would be more like a Long and Strong.rrb6699 wrote:perhaps the sharpest shape with the quickest reaction to friction could be something like 110 x 3 1/4 x 40 maybe 35. I'd have to also see how the pin looks on a layout like this.
Yeah the quality makes it tough, also the camera is set too high off the floor and not really in line with the direction of your shot. Rotation is low. I can see that much.rrb6699 wrote:VIDEO.

not great quality or angle, but, may give you something.

To find your rotation you are going to need to find and mark your PAP.rrb6699 wrote:that blueprint is close to where my initial track ring is.
im gonna measure my AoR next week, re-measure my tilt just to be sure, my speed downlane is 17 avg. pap is different on different balls .
I'm gonna make sure and re-check that now.
That depends on where the initial track is located. What I call a "true full roller" has the initial track between the thumb and finger holes. In that case a full roller layout is needed to reverse the flare migration so the later tracks don't hit the holes. If the initial track is located similarly to a semi-roller track but has 0 axis tilt a full roller layout is not needed, and in fact should not be used because the reversal of the track migration would result in the track hitting the holes. -- JohnPLittleTiger wrote: Good point. On that case 0* of tilt should not cause problems?
Other thing which is interesting in that case is that should these bowlers use full roller layouts what are on wiki or something else?
I can use my spare ball it has no flare. thanks for that input. I don't have any ball that flares more than approx 5"EricHartwell wrote: Rotation is low. I can see that much.
Using a lower flaring or a ball with no flare will make it easier to see and measure your rotation.
When you get your release specs List your PAP from a high flaring ball and from a low flaring ball.
Disagree. I think hes close to 90*. Watch the ball rotation off his hand, not 15ft down the lane in the burn when his ball flips forward.EricHartwell wrote:Rotation is low. I can see that much.
I have seen over 90* drilling angles on this video and on this guide.rrb6699 wrote:perhaps the sharpest shape with the quickest reaction to friction could be something like 110 x 3 1/4 x 40 maybe 35. I'd have to also see how the pin looks on a layout like this.
It is nice that here is also someone else who like to try something new instead just doing things by the book.rrb6699 wrote:I have never tried an extreme layout like this. I think I could learn something from it then see where I can top my sums out at. that's my idea. I have plenty of balls I can try it on that are less than 4 yrs old.
That is why I asked the question "Where is the Mass Bias if the initial angle from Pin to Cg to PAP is 50* or 130*?"rrb6699 wrote:as for the anomoly I dont think it is one. That's probably where it has to be on that ball to achieve those D/A numbers.
True. I don't assume anything. I just say that it is possible on this ball and most likely will be possible on some other ball too.EricHartwell wrote:The Blueprint simulations are for a Columbia Outburst, a discontinued ball. To assume they will be true for other balls is a mistake.
More near of thumb hole but still on same side.EricHartwell wrote:Where is the Mass Bias if you only drill the fingers 2" deep?
If Pin to Gc is anything on guideline (10* - 90*) MB is on thumb hole. With 130* it moves more away from thumb hole.EricHartwell wrote:Where is the Mass Bias if the initial angle from Pin to Cg to PAP is 50* or 130*?
MB location is about same. Initial oil track is move away from thumb/finger holes even with 0* tilt.EricHartwell wrote:What kind of results do you get when using a PAP of 5" over no up or down.
No anomoly as far I know.EricHartwell wrote:What kind of anomaly made the PSA show up that far left of the thumb hole?
3 ozEricHartwell wrote:What did you start with for Top weight that you needed to have the fingers 3" deep.
Let's try. Here we have asym 2 inch pin, 2 oz top weight and using a PAP of 5" over no up or down.rrb6699 wrote:on an assym, if the undrilled ball has a short pin and low top weight, what would that look like?
I don't recommend anything. I just wanted to try if what Eric said was true:rrb6699 wrote:was there a reason you recommend a symmetrical ball?
EricHartwell wrote:Symmetrical it is pretty much impossible to end up with a 110* drilling angle. The Cg could be at 110* putting the thumb hole in the area of 70*-80* depending on your PAP.
I just used this example player from Blueprint and then tweaked delivery parameters to hit pocket and PAP location to get initial track near of holes with 0* tilt.rrb6699 wrote:I can't speak for him, but, he could have used his own specs or an arbitrary set given the sym ball he used as input to the program. if he looked up mine I think they are not accurate anymore.
