I have a sig TI 762 with QD that I shoot on five different guns. The 6.5 is a blast. I would buy the sig again but if I were to buy one today I would consider a thunder beast after listening to the recent podcast from XO Hunt Back Country. If you are consider buying a suppressor I would listen to it. My sig is quite but I might consider a slightly shorter, lighter one that was a bit louder if I were to do it again, especially if you plan on backpacking with it.
I get what you're saying, I've thought about that too. I want something that is lightweight and maneuverable. However, why even spend the money if my can isn't going to be quiet. A heavy can is out of the question for this purchase, but I would be ok with one a couple inches longer. Right now the ones I was looking at was the TBAC Ultra7, Sandman Ti, and the Silencer Co Omega 300. Just wondering if there's better options I haven't considered. 
Appreciate the Podcast recommendation. I'll be listening to that on my commute in the morning.
