RE: Questions from a beginner
Great--at least you have a shop to go to, which is more than most of us have. Big plus!
If they are willing, the shop can get you a left-handed CM to try out. I'm guessing that the 50-55# bows were well above your comfort level. This is NOT the time to be macho--I've seen little guys handle heavy bows, and big guys struggle with light bows. Being able to pull a bow to anchor doesn't mean you can handle it--you want to be able to shoot more than a dozen arrows before it wears you down.
Again, take your time and work into it. Develop good form and shooting habits--this us MUCH easier with a bow you are fully in control of (light weight). You can shoot longer and have more fun with it. Get your skills developed first, then move on to a hunting weight. Lighter bows are fun to shoot and also work great for tournaments and small game hunting. I deal with Chek-Mate myself, and I think they still have a lighter weight left-handed Atilla recurve on hand that your shop could grab for you, if you can't find a good cheap used bow.
I'm sure you know this already, but I'll say it anyway--this is going to be a different game. Unlike crossbows or compounds, where pretty much anyone that knows the basics and can put a sight pin on the target can shoot accurately, this is going to take some time. The good thing is it's lots of fun, especiallyif you do it properly. Don't create roadblocks that will hinder your progress. There are no shortcuts, but you will progress faster by starting out right.
