25-35 knots I go for my 4.7m ezzy panther. I've yet to feel uncomfortably overpowered on it. It's normally the board that feels too big first. So yeah, really stable feeling sail and I can still plane is 15-20 knots with it. 35+ and I'm happy to watch at this stage.
My 5m NP....(forget the name of it)....... it holds such a good shape... has heaps of grunt and loves to marry the Tabou 85 nicely in high winds.......
4.7 2012 Kaos is a ripper, just does it all so easily and has amazing range. If it gets windier a bit more downhaul and bobs your uncle. 5.5 KaRace is going to be a fave at the PiT, so,so slippery and stable.
