Generally speaking, (i say general bc i dont know the rest of your specs) those with Low tilt (less than 12*) will usually find smoother surfaced (2,000 and up) asymmetrical balls to be their best option when they need something to get in and turn the corner hard with. Reason being, is low tilt can essentially be looked at similarly to a rev dominant bowler. Meaning, both have a harder time getting the ball down the lane while retaining enough axis tilt and rotation to provide the energy needed for the backend and pin deck. especially on burnt up conditions. On burnt up conditions, you can pretty much kiss all your strong symetrical balls goodbye, as symmetrics burn axis tilt at a rate of more than twice that of an asymetrical ball.... (im talking pre-drilled symetrics btw, for those who might chime in with the smart *ss coment stating that all drilled balls are infact asymetrical.. I think we all know that)
So if you indeed have what seems like a lot of hand, and your tilt is excessively low (exccessively low i would say below 9*) then stick with layouts that help retain the little amount of tilt that you are able to exert on the ball at the point of delivery. I.E. Pin distances between 1.5"-3" depending on the amount of track flare your looking for-on asymetrics
And PIn distances between 4.25-6" on symetrical balls, again depending on the amount of intended flare.
Please realize there is a lot more to this to take into consideration, like speed, revs, axis rotation, lane conditions, pattern etc. But in general, keep to those basics about choosing layouts to help preserve tilt.
Im the opposite, i need long pins on my asyms. And short on my syms, due to having almost 33* of axis tilt coupled with 65* of rotation lol.
But thats another story
