I have used the standard ruger trigger, the BX (in the US recently, although not in a gun. i actually like that you are able to try them in the package), several mail away trigger jobs on others guns, power custom and VQ kits, as well as kidd and VQ custom packs. for plinking there is very little difference between everything but the standard ruger trigger. for benchrest however, i did notice a difference. overtravel isnt something which i care too much about while benchrest shooting. i do notice the difference in take up as well as pull weight. going from 1.5lbs to 2.5lbs (which is more typical for trigger jobs) is not a huge objective difference (only 1lb), but is a massive relative difference (67%). that being said, paying over $100 more for the kidd single stage than the BX trigger (for example) is a significant price increase (i paid just under $300 for mine).
