I have one and I know it'll sound silly...

If you're running with the same tires you had on at CR two years ago, I'd suggest switching sides (left and right). I think the paddles you have scoop up so much water that you're actually fighting inertia from the water that gets thrown forward when the paddles come out of the water.

I believe that with the scoops turned around (away from the water), they'll actually work better.
