In theory, I guess that the 30% titanium will make it stronger. But then again, I never had any problems with my pre-30% titanium elites. For that matter, I never had any problems with ANY of my scope tubes from Nikon, Leupold, Burris, etc., that are all aluminum.
Don't get me wrong, I just love my Elites, but there's one interesting thing - the new Elites supposedly have 30% titanium, which is lighter than aluminum, yet they still weigh the same weight. If indeed they have 30% titanium, shouldn't they be a little bit lighter? :?
