First of all, great video. It looks like a load of fun there.

I think your tack line is stretching some.

I'm thinking that your not comparing apples to apples with your '97 cut compared to a new kite. In the past couple years I've gone through a 90s spin all the way up to a brand new one. Your spin is cut much deeper and I think your will have a difficult time trying to "follow" that hydros boat.
