Some lose draw length, some don't. I didn't for whatever reason. I checked and re-checked. Dunno. But draw length will only be a part of the equation for which arrows. In the short time I've shot an ASL one thing I've learned (the hard way, as is my custom) is if you got an ASL at the same poundage as your recurve you will likely need a weaker spine for the ASL. With their center cut being further from center they seem to favor a spine group very close to actual draw weight. Of course arrow material, tip weight, length, etc still affects that, so you'll have to settle one which ASL your looking at, draw weight, arrow type and tip weight preferece before anyone will likely be able to give you an idea (and JUST an idea) of what you'll be looking at for set up.
