I replaced the factory trigger on my Bergara B-14R with a TT Diamond and the result is night and day better.
Have you used Jewell triggers? They're the only model of the triggers discussed to far where I've definitely noticed a difference in "pull quality."
But am not crazy about them for general big-game triggers.
The one Bergara I've owned so far had a Trigger Tech, though it was not the Diamond model. They use both TT and Timneys.
