Rattling in bucks in PA will work, but it will spook more bucks than it brings in. You really have to pick and choose when to rattle and when to not. Aggressive rattling is usually a no no. In over 20 years of bowhunting, grunting in bucks, I' ve been very, very successful. I really rely on calls. I carry many into the woods. Amoungst my favorites are the grunt call from River Valley Game Calls, the Woods Wise 6n1 and the True Talker. One to really watch for is the new Buck Flute from River Valley Game Calls. www.rivervalleygamecalls.com
