I shot a 30" draw with a locked arm for about 8 mos when I first started. I was alright, but had the same epiphany ( By way of Gordy at Schupbacs making fun of how I shot) and switched to a bent arm and consequently, a 29" draw. Man what a difference!

Do you think your draw will change at all? Maybe shrink it 1/2" or so and see how it feels with the new form.
