I need help to decide,

ive vet narrowed my choice to a avl58 or storm system. I like the look of the dji system as it will fit easily with my f550 kit and the iosd mini will also install well. But I'll need a can hub and other bits so not cheap.

I like the way I can take a video output from the zenmuse control box so no wires on the gopro...

Any suggestions on before I buy?
