I hope this isnt a serious question because theyre completely different. If it is a serious question:
Prodigy 4.0 is 112 underfoot, CT is 122.
Prodigy is rocker camber rocker, CT is rocker flat rocker
Prodigy has heavy taper, CT has none
Either one is going to be solid in crud because the Prodigy is on the heavy side and the CT is a machine in anything
