If you plan to buy a bow you're going to shoot for a long time, I'd recommend a takedown recurve. Most all of them have good mass in the riser, which makes for a stable shooting platform. And there are quite a few that have optional longbow limbs.

You can put sights on a traditional bow (you'd be shooting against compounds in 3D though. Sights aren't allowed in traditional classes), but I've had serious problems with noise when I tried to shoot a stickbow with a release. Sights on a longbow.... eeeewwww! Not very kosher. They're not quite so out of place on a recurve. Just simple pin sights though. Electronics and wood are definitely replusive.

For your draw length, 60" is fine, maybe even a tad on the long side. Longer bows are more stable and give a bit better accuracy, but you're talking fractions of an inch better. Tournament grade stuff. You have to take maneuverability into account for a hunting bow. Plus, guys with a sub-28" draw really need shorter bows in order to load the limbs properly and get full performance. I'd say a bow that measures double your draw length is a good rule of thumb for a hunting bow.
