I know there have been several posts on this topic, but I am looking for recommendations based on my current arsenal and profile.  I was thinking using 5 x 3 x 2 3/4 buffer on both for breakpoint control.  Any thoughts?

PAP - 5 3/8 - 5/8 up
Speed - 19.1 cats (off hand)
Speed dominant
Revs - 400-450 cats
rotation - 55+ degrees
tilt - less than 15*

Current Arsenal:
Storm:
Gravity Shift - 5x3 (2" val buffer)

Roto Grip:
Rogue Cell - Undrilled
Cell - 4 1/2 pin up x 4
Cell - 5" pin down 45*
Cell Pearl - RICO
Cell Pearl - 5 x 4 pin up
Neptune - 5 3/4 x 5 pin down
Pluto - 4 1/2 x 3 1/2 pin down
Mars - Undrilled
