I have a 139 Harley Grind that I just got. I tested a Harley regular base for about 1 week before I bought the grind. I assumed there would be no difference between the 2 other than the base. For some reason I bury the nose in the wake on the grind whenever I do a backroll or roll to revert and also catch it more on a few other trick but those are the ones that it is most noticeable on. I usually take a really short hard cut on those tricks.
This only happens when I ride with my bindings all the way out which is where I am most comfortable riding. If I move them one in from the last hole then it doesn't happen. I also have this same problem on my regular base S4 138 but... I also have a 139 Lyman where I ride all the way out and never bury the nose on that board. So I don't think it's my cut plus I've been doing those tricks for 10+ years and never had that problem.
The Harley kind of makes me mad since I tested it and didn't have the problem originally. The only difference I can see is the SX slider fines the grind comes with vs the RX regular fins. I'm going to try some RX fins to see if this makes a difference.
Does anyone else have any similar experience with these boards?
