I have a Templar Tactical Nemesis30 which is ti construction and is short (6") and light (11 oz), and I'm pleased with it. It quietens down my 12.5" 6.8 sbr enough so that I'm pretty certain its hearing safe, but I bet it's not as quiet as some of the other cans out there. It is my first & for now only rifle suppressor (until the elusive Ident MkIII gets here), so I haven't had a chance to compare it to sound reduction of other cans. But I took hdfireman's advice and went with a comparatively expensive ti can, and am glad I did, as my suppressed 6.8 sbr is about the same length and weight of my 16" barreled 6.8. If it is to be used as a range toy I guess this is not as much a factor, but for night hunting/stalking & getting in/out of vehicles a lot, I decided that, at least for me, smaller size/weight trumped overall sound reduction/cost.
