953 or Ti?

Its frikkin obvious! Just ask yourself one question, punk. Did they use stainless steel for this??!

Huh, mufucker?! There's no further debate required. Using stainless would have been silly. Like the Ruskies.

nope.....but they did use 531 to make the jaguar D-Type chassis and I read that 953 is used as a layer in bullet-proof jackets...also:
Peter Thompson from Carpenter Specialty Alloys (Reynolds’ material supplier), 953 stainless alloy is twice as strong as titanium with a frame weight comparable to high-end aluminum, and won’t corrode.

But if you are worried about dents, surely you specify a greater wall thickness no?
