The original Trektop was nice but, if you do a lot of highway miles out in the desert or open country where it's windy, the top tends to billow up and pull the Velcro off the sides of the door surrounds. The new Trektop NX is simply awesome - fits better than a factory top in my opinion and is super quite. I love the fact that it converts easily into a safari top and still has the sunrider option. Regarding the top support tabs breaking, you need to slip them on from the side and not try to force it on over the top. Never once had a problem with mine.
