Hi!
Being a pylon racer for 25 years or more I can assure you that most pylon racers world wide fly mode 2.
This comes natural because it's much easier to control one stick than two.
Mode 2 is more like the real stuff as you fly a plane, full size or model with either a stick like all WW fighter planes (and modern fighter) and control rudder and throttle (not so important functions) with whats over....mostly your left hand where precision isn't that important!
