sheesh123,
One "concern" that I have noted with power flying after much gliding has been an occasional tendency to try to "rescue" a poor approach rather than simply go around.
But then flying a glider really makes you use the rudder pedals, which is of great benefit in a SEP.
PPL training gave me a heck of a lot more structured NAV, met. and R/T training than gliding ever did - and all these things are useful in gliding.
