Re: standard shortboard with quad set up?
I'm 200lbs, at one point I thought of taking all my surfing to quads, so I had a 6'6" x 19 3/4" x 2 1/2" shortie made quad. Found it made it really easy to catch waves, much easier than my thrusters, but dissapointed me in bigger surf by having a lot of tail slide on the wall. Ended up getting bigger back fins to counteract the slide but then it seemed like my other thruster, so I sold it. I kinda wish I still had it, I would only suggest you buy two sets of back fins, one for steep big days and one for average to small days.
I ended up getting a 6'3" fishy board like drowningbitbybit does for my small days or big mushy days and a 6'5" thruster for my beach breaks and steep/hollow waves.
Also having two custom quads made, hoping I can dial in the paddle and glide with the hold up, will post up when I pick them up. But yeah, I think it's a good idea to go quad.
