A heavy trigger can throw off your shot if you're not used to it. I experienced this while using a V-Trigger w/ PDI 300% spring in my VSR. I've since swapped to a PDI 200 spring, and it's much better, bolt pull is also easier.
One other thing I'd recommend for your rifle is a 90 degree piston and trigger/sear system. I'm sure that will also help with the trigger pull, and the sears and piston will last longer, since they won't be eating away at each other.
