One that covers the entire side and maybe another version that only covers the curved knee area partially?
What do you mean by the entire side? Most of the tank grip products I've seen are applied only to the scooped-out area of the gas tank, by the seat.
Wait a sec, upon second reading I think I know what you mean. I thought initially you wanted to cover the side of the tank all the way from the seat to the front near the triple-tree. That would've looked strange.
What product brand were you looking at, Tech-spec, Stomp, etc.?
