Are you going on reviews, or what your ears say? Because we test them side-by-side, and as 7" cans go, nothing beats the TBAC ultra 7 for dB or tone. The Griffins are also heavy, being all SS, and have only 6 baffles if memory serves. I know I found it unpleasant to my ears on a 20" .308, comparable to the SDN-6, which is a good can, but outmoded.
TBAC is the cutting edge, Cadillac stuff for centerfire rifle. I'm partnered with an 07/02, get to play with dozens of different cans (includuing stuff not even on the market yet), and I wouldn't buy anything else for centerfire rifles. The weight, dB reduction and tone are second to none. SiCo harvester is about the only thing lighter than an ultra, and it's not capable of handling the abuse an Ultra will (or any other steel or Ti housed can).
I understand being attached to what you bought, and I understand that most don't have the opportunity I do to try out dozens of different cans, but we do ourselves and the community a disservice to be biased to what we own whilst dismissive of what else is out there. It's human nature, but gotta keep it in check. I'd love it if I could honestly say my SiCo Hybrid was a great investment, but I should have ponied up to buy an Osprey .45 and an Ultra 9, because the Hybrid is rather lackluster in one capacity or another on everything, owing to it's Jack-of-all-trades,master-of none design. The only reason I don't whole heartedly regret it is that there ain't many other options for suppressing hot .45-70 loads or other big bore rifle rounds. But it's heavy, especially on a handgun. It's suppression on .30 cal rifles is so-so, .223 SBRs are still obnoxious. 9mm super sonics are unpleasant through it, and my full power 10mm loads (180 gr. @ 1,300) sound about like unsuppressed .380. Just not all it was cracked up to be. I bought before I had the opportunity to test so many others, and I thought it was great.........until I had the opportunity to test so many others.
