Keys SUP said...
I thought the Blade was their flatwater board? No problem as the water is mostly flat in the Florida Keys.
The Blade is also a flat water board.. It's more of a serious race board than the Slice..

Looking close at your pic I can see that you have a hand hole in the center of your board so I would not worry about fitting a side handle as well.
The side handles are mostly used for racing where you have to run while dragging your board to the water at the start of a race.
