I recently used the NSP boards while on holiday and they paddle nicely and are pretty manoeuverable (I could just about cut back on the 9'2 and it is the longest board I've tried). However, I don't think they're worth their price tag new.
I'm on the lookout for a longer board now. I'm actually going to be staying near Scarbs the first May bank holiday so if there's any surf and you'd like a surf buddy you could try my 8'3 single fin (Local Hero Glide and currently my longest board), just to see what you think. I also have a 7' magic carpet and a 6'8 egg and you'd be welcome to try any of them if you want to get a feel for different boards.
