RE: What does brace height do for you??
VOZ:
Do a wingspan method for draw length. With your arms fully extended with palms out, have someone measure from one fingertip to another. Take that measurement, substract 15, and divide by 2. This will be a very good starting point for draw length.
Example: 70 - 15 = 55 55 divided by 2 = 27 1/2
I usually find that what you determine by this method + 1/2" will get you correct.
Good luck and welcome to the sport.
