Traditional archery is addicting, becareful. I picked it up 4 years ago. It brought back the kid in me about archery hunting.
Everyone has their own opinion on whether to shoot longbow or recurve. I use to shoot recurves when I was younger, great shooting bows. When I decided to go all traditional I picked up a longbow and never looked back. For me I liked the way it felt in the hand better. That is the big thing with traditional, as with a compound. You really need a bow that fits your hand. Usually the risers are cut different from one bow style to the next.
Choicing a draw weight. You want to start light. Most will recommend in the 40-45# range. The lighter the better. This will ensure that when you are first learning to shoot the bow you are keeping with proper form. Form is everything when shooting traditional. If the bow is too heavy for you, then you will not get to full anchor before releasing arrow. This will affect your accuracy in a major way, and make you get discouraged with shooting.
As for arrows. A good aluminum or carbon that matches the bow is great. For just learning to shoot you will miss the target from time to time, this happens. And as you know arrows can run you mild to wild.
