I guess you're right about AntiGravity Gear aluminum. I have found that aluminum dents more easily than stainless. You don't have to worry about the pots failing. I've never had one develop a leak, no matter how beat up they were. Remember that really beat up, blackened pots are the height of cool on the trail. Also you do not want to be cooking anything acidic in aluminum.
Titanium is a little stiffer than stainless, but is alot thinner. I haven't used aluminum for years. My Mom heard that autopsies revealed that alzhiemers sufferers had elevated aluminum in their bodies and sent me a bunch of stainless pots and pans. I switched to stainless until going to all titanium about 3 years ago.
You'll certainly save on weight with titanium, and the metal is very inert. No rust or worries about acidic cooking.
