I love set triggers and have never had a problem with them myself. I have had new (to set trigger) shooters find them awkward and wanting to immediately cast them off as unusable and unneeded. After a bit of a lesson and some shooting I don't think I've ever found anyone that hasn't come away with at least a slight affection for them.
I've always gotten a kick out of shooters saying set triggers can't be easily or safely used. Put it in the same catagory as a double triger SxS,,many feel they aren't useable either.
One thing I did notice with a new shooter using a DST is that they tended to try and still squeeze the trigger no matter that it was only an ounce pull or so. Give it a nudge when you need to send the shot.
As far as the accuracy thing, I've already stated I find them more accurate for me than the regular trigger. But everyones different and I couldn't compete with a benchrest shooter anyway.
Besides,,a German sporter or a Mannlicher Schoenauer just don't look right without 'em.
