Well, I trashed my bicep for the second time this year and have decided it's time to finally move from 16 to 15.  I want to simplify my arsenal for next year. I bowl on challenge shots mainly and will sub in wall shot leagues. I am fortunate that my pro shop will take all my 16s in trade.

Stock shot is:
Rev rate :400
Axis: 5-3/4", 0
Avg speed:16
45' axis rotation

I currently have:
Marvel-S
Crux
Crux pearl
Hyroad
Iq tour
Wrecker
Tropical breeze
Pitch black

Thinking of going this way with 15s to start.
Marvel-s
Crux
Hyroad
Lights out
Pitch black

Any educated opinions would be greatly appreciated.
