I have a 36ft center console that can be quite a pain to launch and recover on some what of a low tide with my carpeted bunks. I was wondering if the bunk slides help out at all, or would you guys suggest the liquid rollers that come in the spray can. Most of the bunk slides i been looking at are only rated for about 2000lbs or so, so i'm thinking they are designed more for smaller boats.Any of you guys have an opinion on the spray can stuff?
