I flew both with the contra power. With the contra, I concluded that the M-14 is better without the canalizer.It is just for me and when flying AMA Masters.I think the canalizer is good for extreme knife-edge maneuvers like FAI-F and unknowns.The rudder mixes are practically zero in the M-14 without canalizer.With canalizer the mixes are higher but goes to almost zero when doing knife edge loop for example.I would like JM to build a canopy with not canalizer and save some reinforcing weight.I need to contact him again.
In this conditions snaps in both planes are similar.This is my opinion and could change a lot between different pilots.
