If you shoot instinctively, I would go with the PSA, as that is what it was designed for. I would also go for the 62" length, although that is a bit on the long side for a 28" draw, according to their specs, because a longer length will be a tad more accurate for a target bow. You could even consider a 64" PMA, but I think the 62" PSA is a good compromise between performance and stability. 40# is a good weight for a target bow for someone used to pulling 47#. You have to be able to pull a target bow with good form after a hundred shots, unlike a hunting bow where really only one shot counts (albeit a shot when you may be cold and cramped, so I wouldn't overdo it there either).
