Looking for opinions on soft top material. SO there is vinyl, mohair, Canvas and twill or some could actually be the same material (mohair-twill). Does anyone have experience with any of these? I am choking on the Robbins top cost and Prestige actually has a canvas top that I have read people are happy with. The others mohair from Rimmer (mohair with liner included) and twill ( lost the link) Anyway, what say you?
