They're beasts but obviously there are a lot of sharp objects to hit should you get into a rollover situation. There's a thread somewhere of a guy that rolled his with a hardtop (someone hit him from behind on the side) and he made out fairly okay.
Make sure you get one with dual circuit brakes or do the modification yourself
