The issue with TTs is in Rems, it's from the bolts having such a wide range of manufacture and the TT not having an adjustable sear engagement it will fail on a percentage of them. When I was doing a lot of triggers I'd slam the bolt closed running fast and a percentage of TTs will fire, just the way it is, you can change them out and you'll get the same thing.
I really like Timney's, fully adjustable and been rugged, Jewell's are more sensitive to environmental conditions. BixNAndy has a good following but I never got I to them but have shot them on bench guns and their amazing.
