First- have fun! And that's an order.

Recurves are easier to learn to shoot, especially if you're already used to compounds. Lonbows are fun, but can take a bit of getting used to. Well worth the effort, though.

Arrows- stick with what you know for now. Aluminum is cheapish and reliable. I swear by GameGetters (I or II, doesn't matter), but Jazz is good too if you can stand the color.

Woodies- I shoot them because they can be very cheap (if you build your own), and also because local competition rules prescribe their use.

Get some books and videos too- Fred Asbell's books are classics, and Byron Ferguson's 'Become the Arrow' book and DVD are worth every penny.

Then shoot, and shoot some more, Trad is addictive!
