Played 2 long sets of singles today and 2 long sets of dubs after that. I used the Hex Comfort for 1 set of singles and 1 set of dubs. I did the same for the B Power. So I think I have a good feel for these 2 strings now.
Unfortunately, the Hex does not have any extra spin versus other multis and it moves around like crazy. The bright spot for this string is ground strokes, I felt really confident in rallies.
The B Power was a little more inconsistent on ground strokes. I did like it better on serves where I was able to get a little more pop.
Everything else was fairly average with these strings. Nothing exceptionally good or bad.
