I have been using Timneys now for quite a while about 5 years or so I guess and have not had an issue with them as of yet. Around here in cows arse nowhere I can walk in to my friendly local gun parts store and buy a timiney ,not so with a jewel I don't really feel handicapped even though jewel is top shelf no arguing about that. I right now have the itch to have a rifle built and if this itch gets scratched this year I might just go with a jewel as it would be a minimal part of the cost for a purpose built stick.
You deferentially won't regret the Jewell trigger. I guess it's not fare for me to speak so good about the Jewell triggers cause I've never had a Timney trigger but i can tell ya if you have a Jewell trigger DON"T put your finger on the trigger until you're ready to fire
