The race-weight hood would definitely bend under any kind of spring pressure - they are designed as lift-offs.
But this one is intended to be used with the stock hinges, although with lighter springs shruggy
It's relatively heavy-duty (28 lbs weight) and I'd be surprised if it would bend with appropriate springs.

Anyway I'll probably make a prop rod rather than go to the trouble of attempting to remove the hinges and change springs again with the fenders on.
