I am putting together a 4-5 ball arsenal for my daughter.  She is a 210 avg. tweener who bowls competitively in league and tournaments. She will be bowling the Queens and Women's open in 2015.  Her current stuff is a few years old with hundreds of games on each ball.  I am thinking one hell of a Christmas!  She is a small but gets a decent amount of hand in the ball.  I'm guess 350 rpm, about 15 mph off her hand, 45 degree tilt (hand and elbow on the inside of the ball throughout the swing - hand slightly outside at release.

Current thinking - (all pin up)

Sinister probably at 3000, favorite asymmetric layout 4 X 4
Disturbed - box 2000, 5 x 3
Wrecker at 4000, 5 x 4
Uproar box polish, also 5 x 4

Thoughts?  anything else (other than plastic spare ball)?
