My BIL had a Lux (I think) on his old truck, and while it wasn't all that heavy, he said it was really hard to put back on. It required two people to make sure he didn't scratch his truck putting it back on. It looked good, but was just too restrictive for his taste.
I've ordered the Diamondback SE. I don't have it yet, but from what I've read, it is about as close to water tight as you can get without going to a one piece hard top. The look isn't for everyone though.
