I switched to a single pin years ago and never looked back. Bows today shoot plenty quick enough for a set single pin to be highly effective. I have mine set dead on at roughly 25 yards. Around 10 to 15 yards its around 4 to 6 inches high and at 40 about 6 low. Of course i shoot my equipment pretty regularly before i hunt so i become very familiar with my set up. I dont even use a range finder and know what 40 yards is and dont like long shots so i normally dont shoot beyond. That way i dont make any adjustments. Kinda like range guestimation on deer. The more you familiarize yourself with your equipment and the more you shoot the easier it is to spot guess the yardage and put the arrow where you want it. Believe it or not i've gotten pretty good on picking out trees and telling you how far they are plus/ minus a couple yards. The pro's for me are see deer shoot deer. Not a whole lot of guesswork. The only con i can think of would be if you liked to adjust it and not use my type of method. It takes a little time to range and adjust but we are talking 10 seconds
