I have never taken my bars off yet. You lose the ability to lower/raise the top while in motion, a
really cool feature if you ask me !
I can't wait until the day I'm driving, and there is a big $$$ convertible behind me also with it's top down, and it begins to rain. I hit the "up" button and continue on, while the big $$$ convertible hits the highway sholder to raise his.
Plus, I'm concerned about the gaskets and such not making a good seal if I keep taking them off, leading to whistles and drips. I don't even know if this will happen, but as of right now I'm not taking chances.
