Rolled a bunch of times, I will take a side roll over a front over rear flop anyday.
That said, I think stingers are stupid. if your in a situation such as the picture above, your wheeling skills need a major reality check, skinny pedal on the right to drive out of it. Regarding roll over protection, I prefer and run a radiator hoop. I find in a rollover, the force applied to the hoop in relation to the attachment point is far more favorable than that of a stinger (90 degrees versus 30-60 degrees)
