Welcome back home, may your journey here be swift and safe. With the sounds of the July Fourth celebration ringing in my ears, your post makes me happy that there may be something that we can do for you.
Your practice upon your return will depend upon your facilities at or near your home. We're it me, I would use a blank bale for form, then a target on it to verify aiming, and then some arrows with Ace Hex Heads on them for stumping and yard games.
You will get all kinds of suggestions for your longbow. You need to decide what kind of longbow, grip type, and what sort of features are important to you. Are you into D shaped or Hybrid RD types? Super speed or quiet power? Only you will be able to say.
There are many TG members in Pennsylvania who would be honored to shoot with you, and let you try out different styles of bows. There may be some 3D shoots that you could attend, also, even if you go bowless. Vendors at such events love to have you discuss and try their bows, hoping to make a sale, yes, but because they love archery, too. It is too bad that you are coming home after the Denton shoot, but maybe crowds aren't your thing. That is a place to shop, though.
Because you are a Pennsylvanian, and because RD Hybrids are popular, and because I love his bows, I will put in a plug for Leon Stewart as an excellent bowyer who can make the heavy bow that you desire. There are hundreds in the U.S. who can do the job for you, and do it well. I mean them no slight, as I have bought from and enjoy the products of more than a few of them, but Leon stands out to me for his craftsmanship, business ethic and values. A pleasure to deal with and he is in your state.
Thank you for what you have gone through for us. We can do what we do only because you did what you had to do in your Service. Now, let us do something for you.
