Let me change up the wording. If you were going to build a car from the ground up, would you start with a Lamborghini, or a Model T? Chances are you would start simple and work your way up. Longer is simpler (In my opinion). If you read enough post here you will soon see that a short bow is always something that people love. It is not for no good reason. It takes pinpoint craftsmanship to pull them off. I have made a few bows, and they all have their own issues. I am six feet tall, I can draw a bow 22, or 32. I do feel comfortable short drawing a bow, some people don't. They say a bow at full draw is 90% broken. Thus building a bow that can draw to 30 inches, even if you never do, is safer than to build a bow to draw 23 and raw it to 24, 10 or 20 times. You have to crawl before you can walk, and you can't run right out of the gate. When I started I had the same thoughts you did. And boy have I had my pride and confidence knocked in the dirt. Have fun. We are all here to help.
