Not IMO anyway. Of course you want a consistant draw and anchor.

If you draw is 29" with a compound then figure 1-2" shorter with traditional, it will depend how you anchor. Most bows will be measured at 28", so you will be right in there.

I draw 29" with traditional and feel comfortable with a bow made for 28", I would go not much lower then that though in fear of having the bow stack on me.

For your first bow, I'd suggest going in the 45# area at your draw.
