I just bought the Rampage frameless soft top, Rampage Windshield Channel, and the Rampage Tailgate Channel with Tonneou (can't remember how to spell it) cover. Impressions... I love it and love the "sporty" look of it! I never had the OEM soft top mounted nor have I ever been in a Jeep with the OEM soft top(original owner included, a bikini top, OEM soft top, and hard top... ended up selling it to help fund the frameless top). The two most selling points for the Rampage was the window storage up top and the fact it can be converted to a bikini top (at the moment it takes me 5-10 minutes to take the windows off and about 10-15 minutes to put everything back on)... oh and the price fit my budget. If you do get the Rampage... a. install it during warm, sunny weather b. having 2-3 buddies help you put it on makes it quite easy to install c. let it form to your frame... it's getting easier as you take it on and off, but the first couple of times are a pain d. make sure the foam pieces are folded length wise in half and put snug against the windshield e. lastly, my buddy who has the same top showed me an easier way to put it on (once the bikini top is on, put all three windows together, start zipping, and then put the bottom in the channel instead of putting the bottom in first and then zipping everything together). Sound wise... from what I'm told it's ten times quieter than the OEM soft top (but like I said I never had the OEM soft top), but I can't confirm that. It's only a smidge louder than the hard top in my mind, but it's not bad at all. Hope that helps!
Cliff notes: I would recommend the Rampage Frameless!
