I've decided to get a racing handcycle and get a little serious about it with a real training plan like those able bodied days of old and that means a power meter. I use Quarq crank based power on my bikes (all standard size cranks unfortunately) and I'm leaning that way now. Anyone here using a Quarq on a handcycle.

Along that line, were I to go with a double chain ring crank what size would you get? I rarely use the granny on my freedom Ryder, but I'm guessing a standard 52/39 set up would be too big...?
