Skated on them today...felt great. Not better or worse...just different...but not by much. Went back and forth between AS3 Pros (7.5 263), 100k Pro (8 271), and Catalyst Pro (7.5 271)...no issues or concerns. Biggest issue was that my 263 needs sharpening and the 271s are fresh. Anyway...appreciate all of the input...as always.
