[pair of jacks]

My boat still has the original fabric t-top cover from when bought new in 2001. Lots of small holes starting to develop. Could probably get another season out of it but I'm considering converting to a thin, lighweight hardtop "skin". Does anyone have any experience with these or suggestions for who makes them? I'm leery about going to a standard fiberglass top because of weight considerations on a 21' boat. Thanks
