I've shot winning scores at Perry with a malfunctioned M1A trigger that we hit with a strip of emory, and I shot for 2 weeks at over 8 pounds...
I've lost with finely tuned barely passing weight triggers too.
Good shooters overcome.
That said, there is NO doubt its easier to shoot with a finely tuned trigger. No doubt at all.
As to feel, I also think that there is a personal ton of difference there... not that you can't get used to whatever, see all the I can't shoot 2 stage threads and well.... they are WRONG.
