Depending on how you do the math I did even better or not as good as you.
I upgraded my batwing. (Sensar II, plus Wingman Plus Sensar pro) Still have the original Batwing though.. Went fro 1-2 channels to over 25 in the same parking spot.
(you got more channels.. .but you had more to start with, On a improvement basis I'm way higher in percentages)
