soilarch, first congratulations for the change. I'm sure you will find traditional very enjoying. Your draw length with trad will usually be 1-1 1/2 inch shorter then coupound. Most shelve bows are set at 28" so you will be right in the ballpark. I would also suggest going with a recurve at first since the "feel" will be a little closer to your compound then a longbow (get that later). I would say go with a 45 pound though. Because if you strugle with something higher it will most likely effect your accuracy and form. You can also go higher later. 45 is plenty to take down a deer. You may want to get a used bow at first, use it a few years and get just what you want.

Also get Ferguson's book. There is a forum started here that you can get some reviews on. It's a great beginner book.

Let us know how you make out.
