Lots of postivie comments ahve been made on the Rampage top since it came out. It really is an improvement from the Kayline/STC versions. You might try a search on the subject to get more specifics. IMO, if installed properly, the Rampage top seals as well as a hardtop...which is pretty OK, but not perfect. The thing to remember about the Rampage top is that it is totally convertible fairly quickly. Windows can be zipped out (for safari-style top) or in for a full top....plus you can drop or raise the whole thing in just a few minutes. Good luck with your choices.
