Tried my 5ft 5 WRF BP with a knub and.....really didnít like it. Felt like it messed up the whole dynamics of the board Ė lost the sweet spot really (which is the whole of this little beauty!)
Hate to be the one to say it, but you should flog the SP and get a BP. I liked the SP but absolutely love the BP.
However, this was in small clean waves and only my opinion. I do tend to like the Firewire boards that none of my mates get on with. My favourite models appear to be making their way to the Firewire archive of doom!
Techno grain BP has to be a life changing board!!!
