I build a 60" hybrid long bow that will go 33" without a problem. but most of the really long draw guys prefer the 62" model.
Here is something to consider.... All bow designs are different. The straight D shaped long bows require a much longer length to get a decent string angle.
But there are a lot of Hybrid long bows or Reflex/ Deflex (R/D) that will handle long draws and perform superbly for you. The thing you need to watch is the string angle at full draw.
Here is a little drawing that will help. There are two angles that are important to consider. The angle of the string where your fingers are on the string. And the angle of the string coming off the tips. The finger pinch issue is a big one on the first one. The tip angle determines when the bow starts stacking up. once you reach 90 degrees you are at a point where the bow is going to get really hard to draw, and getting off the string clean is going to be tough to do.
Here is an example of a 60" Sasquatch hybrid long bow drawn to 32". Look at the string angles on this bow.
I invite you to take a look at what Big Foot bows has to offer in more detail. Check out my website, or give me a call if you have further questions.
