I play the E5 because i do not need the length or straight help with my shots, the E5 spins fine for me and i find no problem with the covers
"shedding" or "growing hair" withuse of the wedges. I have used the same ball onmultiple rounds and they seen to last. most of my shorter shots check fine and they putt well.
I play the r7 425 driver and continually hit them around 270-275 avg and when i get a down hill they fly just fine.
