Reg duplex is my favorite. I had a Leupold heavy and hated it. I had the worst time getting on target.
Wayspr... you can send your scope to Leupold and they will change it for you for a nominal amount. I didn't know that until after I had sold my heavy duplex... had the same scope as you, and sold it to my cousin. He ended up not liking it either and got the duplex reticle put in.
