Well, to make a long story short, after lots of internet research I chose the skyzone 40ch diversity with dvr while they were still $470. I did this based on specs alone and the fact the diversity rx are included standard.
I had only ever used my quanum v2s before receiving my skyzones, and have still never used a pair of fat sharks. My question is this; what am I missing? Especially considering the Sky Zones are now around 3:50.
