I think I heard the besttop tiger top isn't available yet. I'm not sure about that though. I've heard both positive and negative things about the STC Fastrack. I have been waiting to hear how folks like the Besttop, but like I said above. Most reviews on the fasttrac have been poitive. I believe there were complaints about the instructions, but as far as leaking goes they seem to hold out water about as good as the hardtop. I live close to Turner 4x4 and I'll go get one and try it out, but I'll need you to send me about $600.
I'm sure some folks on this board can give you some first hand reviews on the fastrack. I'm glad you made the post. I'm interested in peoples thoughts about these softtops too.
