I'm on a 68" Quest 45 and it's the best ski I've been on in years by a mile Totally factory on the fin and wing but I just went to the D3 site and I see they have updated the settings. I'm at 6.935, .4515, and .750. It's fast, early, stable and I have space. Bindings are 30.5. Now to be fair I'm skiing at 32MPH (65 years old) but for the first time in a few years I can run right up the line into 35 off. I have to let off way early to keep from running too wide.
