Jim,
What are you skiing behind? I ride a BigDaddy in and out of the course. If you're truely stacked you should have no real problem cutting through the wake. I have run the course behind i/o's, my 85 MasterCraft, and even a Super Air Nautique. It's all about being centered on the ski. A big wake is actually usefull in showing a skier if their position is as good as they think it is in my experience.
That being said, to really make the BigDaddy something you can ski that aggressively, I had to lengthen the slot and add a slider fin with foil, and add a highwrap binding and toe plate so that I could play with the binding position to really get it to where I was comfortable on the ski. Based on your weight, with a factory binding placement and no wing fin, I would probably keep it around 25 at most. The tail will want to pop out in the turn if you're getting the tip down, which is what will let such a big ski use it's shape to really carve a turn. Might try a smaller ski, but still shaped to help keep it from being too hard on the body.
