Sorry for hijacking, but how can you tell the difference between the small fins and large fins?
The Sunova fins have numbers printed on them that theoretically correspond to the suggested weight of the rider. So 103s are for someone who is 103kgs, but as a 103kg person, I still think they are too big on my speeed. I use large sized c-drives they work just fine.
Sorry, I meant from a surfing point of view. Do you find it is easier to turn, are you less likely to slide out, does stability change, do you go faster? I am not even 100% why I would swap from thruster to quad let alone why I would change fin size. I keep meaning to experiment with fins within a session (to really test the difference), but once I am surfing I don't want to come out and change fins...
