Short of turning the bow down the speeds of these new bows there isn't much diff in 20 and 30 pins. May be set the 30 to 35 on so on that's what I did.or like I had mentioned take a couple turn out of the limbs and slows it down a little you don't need 350ft per second to kill a deer at 50 yards. I'm not sure what poundage you are shooting I will give you a reference off my bow I have a z7 at 70 lbs I turned it down to 58 pounds still shoots 295fps I shot my deer last year at 49 yards clean pass through. Now sure if you are going to hunt elk ,caribou or buffalo you might want to turn up the heat. But to hunt deer it's not necessary so don't be afraid to turn it down a little to get the pin gap you want trust me it doesn't take but a few turns. I always be leaved the more power and more speed was better but I soon found out consistent shooting and comfort is way more important.
