I have that setup in my 17. Originally I was trying to get rid of the muuuushdoink of the stock trigger so I had combined it with a 3.5 lb connector. The end result is that the end of the slack and release of the trigger were too close and the reset of the trigger too soft....for my fingers anyway.
I went back with the 5.5 lb connector and replaced the striker spring with a 4 lb Wolff so there is a definite step when you take up the slack and on reset. The overtravle stop is nice, it does shorten the reset of the trigger.
I think the only way to get a huge difference would be to make all the trigger components and trigger much more rigid....but you may end up having to make an entire unit out of metal to do it.
Next time we hook up at a range, I'll let you try it out.
