I spent a lot of time bowling on some very dry lane conditions while I was away at college and have thrown a lot of Avalanches and a Groove. I had 2x Blue/Silver Avalanche Pearls (pin up, pin down) and 3x Green/Black Avalanche Pearls (pin up, pin below middle, pin below bridge), and a Powergroove (pin up), so I have some valid input here.
The Blue/Silver used a pearl version of the NControl Coverstock which is very tame, but good for dry and medium-dry lane conditions. It didn't require much oil to hold line to the pocket and was effective on flatter, dry patterns allowing the bowler to play more direct angles. When swinging the ball, I found the Blue/Silver to be a little touchy, but was great for playing the track.
The Green/Black uses a pearl version of the Powerkoil 18 coverstock (same as the Danger Zone Black Ice if I recall, which is a pearl DZ). The Green/Black's stronger cover allows the bowler the option of playing through a little more oil and provides a little more bite through carrydown making it useful on a wider range of conditions. It is simply just a little more ball, but the core/cover combo at least in my opinion match up great!
When I got my first Green/Black drilled I also had a Powergroove punched up with the same layout. I found that at the same finish, the Green/Black was 3-4 boards stronger, beginning to roll a little more in the midlane and having much more backend recovery. The Blue/Silver rolls slightly sooner than the powergroove, but overall they are very similar bowling balls.
