Andrew,
In my former life when I shot a compound (also with fingers), I drew 31". When I "found" traditional archery and started shooting a recurve, my draw was 28". After a few years, I figured out one little thing to improve my form, and have shot 29" draw length ever since.
Once we figure out the form question, our draw length is what it is... no more... no less!
Don't worry about the NUMBER of inches you pull, just that you fully "load up" the bow with proper form, shot, after shot, after shot!
You might consider asking for a good training DVD for Christmas: Masters of the Barebow 3, available from several Trad Gang sponsors. I could have saved five years of trial and error (mostly error) if something similar had been available when I started 100 years ago!!!
