Hey I am looking into purchasing a new (to me) furling 135%. I have the option of Sunbrella cover or a Plastimo Dacron cover. I have no knowledge of the protective ability or durability of the Plastimo cover. I have been informed that it is lighter yet just as effective as Sunbrella. Being that the plastimo is white I am not certain how that may be. Any advantage of lighter weight of plastimo on roller furling headsail?
