meh. not the best.
Two stars seems harsh but when it comes to your hard earned money, lets not play with that. i have a block of the cold for mammoth pow, and a block of warm for local so cal slush parks. not impressed. i didn't think i would be one of those "overly technical on equipment" type riders but it was a noticeable difference. albeit i have only tried three different brands (and i think there all made by the same production facility)
Dakine all temp (came with the tuning kit)
burton all temp.
one ball jay (warm and cold)
the best in my opinion was the Dakine. The lesser of the three was the O.B.J.
Dakine all temp and some floro paste on top of that for warm/slushy days is what works for me. I amm able to keep up with my skier buddies (who purposely go to the flats on me) with the O.B.J. I had to unstrap and skate. Which sucked. Not to mention knuckling a jump, which really sucked. my two cents.
