Cooter browm top here. Had a canvas top, but when going over 10 or 15 MPH it flapped in the wind badly, i tried every way in the workd to keep it tight, would tighten it and the next time i rode would be loose again, plus they will hold water when it rains. They are ok for just a temporary top, but if your buying for the long run, better go with a hardtop.
