yes, prop rotation usually makes a pretty big difference. that said, from my experience Tigés have excellent surf wakes, and seem less affected by prop direction.
i sometimes have trouble getting a good clean starboard surf wake out of my VLX (LH prop, like your boat). it takes probably 50% more weight on the driver side to get the same power in the wake as port side.
Nautiques are the only RH rotation tourny boats, and they are cleaner & easier to build on the driver side.
