I'm still skiing on my older Dynastar Legend 8K @178 and intend to get at least one more season out of it. I found that the factory tune allowed for a nice variability of turn shape even with a natural radius of 20. However, after a full grid and tune I found that I had to do some significant detuning to get back to that kind of versatility. Initially the problem was edges catching at the tip which I fixed with some detuning.
However, the persistent issue was that on steep,skied off/ hardpack where I was looking to slow down a bit I had trouble getting the ski into a tighter turn by allowing the tails to slide out before engaging back into a full carve. On softer snow this obviously was not an issue.
Maybe it's just my technique and having been used to duller edges, but I'm pretty sure that a tune more suited to my style would help.
Thanks for any suggestions.
