What I have found is stainless is more weight, however the titanium brakes are so hard they continue to twist onto the stainless barrel. The are very hard to time. I have 2 titanium brakes and they never stay timed on my barrel correctly. They continually twist tighter on the barrel. I'm not sure if one is expanding and the other can't or what causes it but since I am crazy and have to have everything perfect, I've replaced the titanium brakes with Assassin Brakes from J E Custom.
