Just typed up a really long carefully thought out response and it disappeared... anyway what I said was that I was in the same situation last year, tried 32 off, hit the trough, hated it, went back to 15off.
Just tried 32 off again last weekend, only this time I leaned back, stayed on edge, and felt my ski float right across the trough. It was like I truly slalom skiied for the first time and I can’t wait to get out there and try it again.
Long story short, 15off is a speed bump, 32 off is a trough, it’s much easier to skim across a trough than a bump. Key is to just go for it at full speed and you’ll feel your ski glide right across the gap.
