You are right to get the poundage down, and longbows and recurves pull the same at full draw, so don't add five or six pounds....that is not the right thing to do.
I would not go above 45 pounds to learn form. That is almost too heavy in itself, but 45 is also plenty for any game in the USA. Learn to shoot accurate first, then if you want to increase poundage, do it a few pounds at a time, not in big steps. I've been at this nearly fifty years and there are few shortcuts to accurate shooting. And, being overbowed, is the worst thing you can do.
