The GXRT (GrinderX round tail) comes from the GrinderX platform. When the waves get a bit bigger, faster, and hollower the GrinderX starts to 'red-line' with the wider tail and tail block, so I refined it out and this is what a came up with. I added a bit of tail and nose rocker. The outline has a slightly narrower nose and the back third of the outline was blended into a smooth rounded pin tail. These refinements add up to a board design you can just jump on and ride in better waves if you are riding more grovelley boards on a daily basis with out wasting half a session getting used to a 'step up'. I'd suggest going and inch or so longer than the GrinderX.
