Yes, absolute kudos to all glider pilots, far more skilful than us noddy pilots - but it depends on what you want to do, whether you need to go places, etc. I did start gliding at first, but it was an all day affair, and sometimes after helping everyone else, I still didn't get aloft. Switched to powered and never looked back, but still practice gliding every now and then for PFLS, and on one occasion it was the real thing!
