I'll have to go against the grain. I've had several 60" bows over the past 20 years, all with medium risers. They're the perfect length hunting bow, especially for tree stands.
A couple years ago I picked up a 62" bow with a long riser. Most often a longer bow will draw a bit smoother and this was no exception, extremely smooth. What really surprised me was how stable and forgiving the bow was to shoot. The added mass weight and design of the bow made it incredibly accepting of release flaws or bow arm movement.
With that said, if your looking for a great all around hunting bow I'd agree, a 60" would be a fantastic choice. If your primarily a 3d shooter, who also hunts I'd give the 62" bow a look. I think you'd be pleasantly surprised.
