I ski on a sixam 1.1. No ventral. Working on 22 off @ 34. I can run 32 mph pretty consistent on my ski. My fin is set up all stock.
Today I didn't have my gear with my so I rode a friends 1.0. I went out the front twice @ #1 ball. He has the ventral on his ski but I'm not sure how the fin is set up.
So.. What is different between the build of the two skis and what is could be different to make me go out the front so easy.
