Unfortunately, put me in the group that says it can't be done with 900G covers. The C/2 Pearl is my second-favorite Lane #1 ball behind the Tsunami, but what made it that way was in large part to the core/cover combination of that core and the Brunswick coverstock.
Every Lane #1 I've bought since the switchover to the Columbia, then 900G plant has been more angular than I expected (Evo, HRG, XP) and that's not always a good thing.
Just as Brunswick has lacked a nice-performing truly angular coverstock for sometime, I've yet to find a heavy roller from 900G.
