HV-Maxx or something else?

I'm currently running an 8XL with a 9920 in an 11 pound truck with 14/51 gearing, a strobe slipper and 5s lipos. I have not even attempted to up the gearing yet but I will once I can drive it at this speed which I would put at about 40mph. I previously ran an HV-Maxx system and like others have said there is no comparison. In addition to everything else the system just runs cooler and I get 20+ minutes of run time. Like others told me when I was asking these questions, you won't be disappointed with the huge upgrade in performance.
