I installed my ST Turbo fins and IMHO they make quite a bit of difference. Keeping up with a fast moving school was easy. After I'd find them I'd call the rest of the bunch over and they'd start casting. What I tried today was pulling two yakers back to the launch. It was soooo easy. I wasn't breaking any speed records, but I never got tired either. It was cool hanging on to a yak with each hand and for steering, one of my buddies would put their paddle in the water to keep us in the right direction.
