If you get a Mentor make sure he is actually a good shooter, no reason to learn a bunch of bad habits. Byron Ferguson has a book and video that is good intro to traditional and goes over all the basics. A really good bow set up and arrow tuning video is on youtube by diamondback archery. (Sponsor here). Its the video that starts out setting up a recurve them moved to shooting arrows at straw bails to group tune arrows.
My tips dor you:
Learn good/proper form, attend Rod Jenkins clinic, get a decent bow that is not too heavy or too short, learn to group tune your arrows since bare sheft tuning can be tricky and frustrating, get good arrow FOC. 200-250 grains min. between insert and head, learn what blank bale shooting is to practice form, dont practice every night if not quality practice, shoot three under and use a fixed crawl if wanted, attend at least one shoot/Rendezvous a year to meet bowyer, Trad guys and shoot ofcourse. Several shoots in Virginia, Maryland, Ohio,Tennessee, Kentucky and Indiana that are driving distance from you. If you want to talk them PM me. Good Luck!!
