HI Scott, Welcome to the Gang!
Recurves are the most common transition bow, but if you have a hankerin for a longbow, it's OK to start there. Keep the draw weight light for your first bow, between 40-50 lbs at your draw length, depending on how much you can handle EASILY. Nothing will mess up your learning curve like trying to shoot a too heavy bow so if there is any question, go lighter. Most bows are weighted at 28" and you can add/subtract 2.5-3 lbs per inch either side of that. Some customs are weighted at the buyers draw length, so pay attention to that. You will go thru a few bows getting started, so used is a great place to start. When you figure out what you like and what works for you, then think about new. You're gonna need arrows, too; more choices!
