I think I will surf it in thruster configuration initially just because I haven't used one in a long time but thinking maybe switching out fins in certain conditions if I ever notice enough difference.
This is my take on quads after riding them 15 years: I usually surf size 5 in front and GX centers or sides in back when I do quad. The smaller size fins means less drag and the board just seems to glide right throw slow pockets, but when it gets steep and I try to cut back hard the tail slides some, which I can compensate for and turn wider. With the quad I feel like I can catch waves easier and paddle around faster. With a thruster set up the bigger and centered back fins cuts out the tail slide, but the center position and bigger size creates more drag so I used it on bigger & steeper days.
It does beg the question why not just use bigger size back fins to compensate for the tail slip, and I've tried different combinations, M3's in back , double 5 centers, etc... which I have tried. The result is that when you do bigger size back fins you end up with about the same feel as you would a thrusters, so stopped tinkering with it and do as I stated above.
I was watching a surf video and Slater was using a quad with big back fins at Indo, so maybe he figured out something I didn't. Then again, I don't surf Indo and I'm not Slater LOL
