i am assuming the front spreader is set up and back so you can still run the windscreen? those front corners WILL fold in if you hit them hard. all the stuff around your head (the important stuff) will hold up well. the diagonals through the roof would be nicer if they ran right into the corners, but they can't due to the front setup.
it will save your life, and it will stand up to alot of hard flops. but after a hard roll you are gonna have to tweak the front of it straight again.
