hammer,
do not sell yourself short dependant on mostly high end stuff. A good arsenal would be:
1. Big One
2. Overtime
3. Black Ice
To set an arsenal on only 3 balls, go with variety. Do not go for 2 high end and one low end simply because of what someone else here mentioned in that you leave a HUGE gap. Go with one high end, one mid performance, and one lower end. That way there is enough gap between all 3 balls to hit just about every lane condition.
