I always use thruster setup.
Dont like quads - feels like a TT or raceboard to me, tracks too much eventhough often better upwind - and the "surf" feel when you turn on the wave is lost (at least not as good...), even with smaller fins, in my experience.
But many like quads because it feels more skatey and TT like and better upwind
If you dont know, you wont feel the difference for a long time, so just choose what it got now then, easiest
And try it yourself when you CAN feel every small difference, later
But beware, fin sizing and profile and stifness and topflex is just as, or even more, important !
