I have a friend, adult female 50+ 4'10" tall maybe 100lbs.

She uses 12lb stuff. She is a very competitive person who needs a dynamic ball.

She uses a Victory R and Maximum Velocity.  I know at 12lbs it is mostly coverstock you are paying for but are there any balls that seem to work better than others?

thanks in advance for your help

I suppose most impact comes from a proper drilling. If the ball matches your game, even a Power Groove can rock the house! Not a performance ball, but a deadly weapon when used the right way.  

A female fellow bowler (quite small and thin) also uses 12 lbs. equipment, and she plays very slowly and not with many revs. She has a Power Groove for dry to medium conditions, a battered Ebonite Tiger which moves rather arcy and an Eraser Boost for heavy conditions. It is amazing how strong the EB breaks for her - but it is her low speed that makes even a polyester curve 5 boards...
