Hi Juandesooka,
Thanks a lot for the information, definitely there is a lot of information in the other forum.
I willl probably go for the rs1000 and use it on the bigger days.
I have been using the RS1300 for SUP and wing during a few weeks, and I don't see myself dismantling the wing. I can haddle up 1,5 meters waves with no issues, carve turns and the pumping is awesome.
