Couldn't agree more. For pure flying, gliding is far better IMHO, and the whole weekend, 10 minutes is a little unfair! Once you get the hang of it, and pick the days 3-5hr flights are quite normal, can travel decent distances, suprisingly quickly. And glider aeros are great!
On the other hand, spamcans have a certain convenience factor, and going places is somewhat easier.
But then I'm biassed - been gliding for 2 years, currently mid PPL.
