Basically the higher rev players will like the higher degree angle sums, say like a 90* pin by whichever pin to pap by 70* mb. the highest for the first degree is 90, lowest is 10. highest on second degree 70, 20 lowest. Now those are just save zones for those measurements. lower rev players like the lower angle sums, 10* pin and 20* mb for the really speed dominant player. basically you get the angles you want by defining which type of bowler you are, and what kind of reaction you are looking for. The 5 types of players are:
1. Speed highly dominates revs
2. Speed mildly dominates revs
3. Revs and speed matches up
4. Revs mildly dominates speed
5. Revs highly dominates speed

A number 1 type of player wants the ball to read the friction as soon as possible with the quickest response to friction (10* pin, 20* mb).A number 5 wants the ball to have the longest reaction while having the longest response to friction (90* pin, 70* mb). Hope that helps.
