Thanks for the input guys. I have a PG .555 and a PG .570. I am leaning towards the .570 right now, just to not have it too dang tight close in. I also just picked up a JH .570 to try with them. I just have to wait and see when I pull the trigger on the 3 chokes with the nitros and see what happens. I'm sure the PG .555 will be the numbers winner for sure, but if the .570's get in the 180-200 range, I will hunt with them in a heartbeat over the .555.
