There's a lot of good information in Soft Top HELP!!!
On page one, there is a good review of the OEM tops vs the trektop that was written by Nuke83. He owns all three, so you get a real person's thoughts.
I believe once you get the hang of taking the tops on and off, lots of guys get it down to being done in just a few minutes. The more you add/remove, the quicker you will get... Jeep tops, that's all I'm talking about, guys! JEEP TOPS!
