Going longer rather than to a wide?
I wear size 11.5 boots, so not real flippers, and I see some longer standard width boards have a waist width that should be large enough (258-262mm) to handle my feet without drag. The board I'm on now (160cm K2 Raygun) has a waist width of 265mm, and I want to step up in length with my next board. I'm worried that a 164-166 wide is going to be TOO wide to be nimble. Will something like a 165-167 standard width board with a waist in the 260mm range be better?
