If it can't be done on deer with a 47@27 Ghost, it can't be done. Buck fever or the general anxiety of taking a hunting shots, can bring out some goofy stuff. I tried three under with a 50" 49 pound Browning Cobra way back in the 70s. What worked well for me out to 25 yards at a target, turned clumsy when shooting at a deer. I had to put the nocking point about 3/8" higher than what the bow required when shooting split finger. I am pretty certain that the two shots I took at deer with that bow, I strong fingered the shot, wild arrow flight and clean misses. I found out about adding the elevated arrow rest after I gave up shooting three under. Killed a deer later in the season with a BW metal riser takedown, shooting split. Metal handled bows like that are finger freezing machines, but that particular bow was very quick and very accurate on still targets. I think I get too much of an adrenaline buzz when i shoot at game, I tend over draw when shooting at game, so I use my broad head as a draw check, and yes i did pull an arrow off the string once with an 89 pound Hill longbow, it takes practice.
