I'm with you Duffy, we are snowboarding mostly, but when the sun pokes out I want to hit the lake.
My understanding was that the '07 WWSC was pulled by two 230's both with 'blades. One regular rotation and one reverse rotation for the darkside wake.
The WWSC website has some pictures, taken by Vince, here is a link to the activity on Saturday
Just a few pictures: the regular side boat, the darkside wake and then Todd Gaughan on the regular side wake. NOW...Todd is FAT as a HOG, so the wake is actually larger than it appears because of Todd's immense girth.
