Very different boards. I'd even say VERY
But no I've only ridden the former.
what are u looking for it to do..?
For an at home board I need something for light winds and cross on conditions. But my favorite travel destination is Pacasmayo which is cross off, but still light. Would be nice to have a one board solution, but I guess nothing is ever going to cover both cross on and cross off and not compromise on one of them.
So far the best all around board I have ridden is the Quatro Cube 106 L. But I need an extra few extra liters. Phenomenal in cross on. I took it to Pacasmayo about 4 years ago and even there it was a great board, just a touch too small. I am guessing 112 L would be perfect.
I have the 113 Pyro. It's incredibly fast and if you are on the taller side and have the weight for it will turn like a smaller board. I believe the Stone is a bit more aimed as cross-off down the line conditions.
I have now sold all my other wave boards and use the Pryo 113 exclusively with 5.7 down to 4.2 sails.
Edit: don't know were you are based but the 113 Pyro might be a custom order. Here in Western Australia most shops don't seem to stock too many wave boards in the 110l plus range.
