I also have a Reflex Excursion, 60 lb pull. My groups tightened up dramatically after I paper tuned my bow. I'm not a target shooter, so I don't know how big a 10 ring is, but I've been able to consistently put six arrows inside a 2 1/2" circle at 20 yards. I'm using a shoot through rest and fixing to change to a drop away. I don't like the idea of any potential fletching contact like in a WB. Also, having a sight with a level bubble has really showed me that I was torquing the bow, even though it is distracting at first.
