Splitting hairs if you ask me when it comes to longer d-loop vs draw length. Do whatever it takes to get you to your proper anchor point. Everybody has "the sweet spot". This will vary bow to bow...don't just trust the bow's label on it. Some manufacturers run long on draw...some are true to AMO draw length.
Elite and Strother are two that are dead on AMO. I actually had to move to a 28.5 cam/module on those bows to get me where I needed to be...vs Mathews and PSE where I always had to go with a 28" cam to get in the right spot.
As for getting draws longer than 30". There are a few companies that offer such bows. I'm looking hard at a Strother Moxie for an all target bow, and just because it's top of my head, I know it goes to 32" draw length.
