Also it's not an 'either or' situation. I've just rejoined my old GC, the last time I flew a glider was three years ago. I'll probably do it for a year, thoroughly enjoy it and pack it up again for another few years. I'll still fly powered of course but I think I can just about squeeze a Wednesday maybe three times month at the GC. I just fancy poling a glider around again, when I get fed up I'll pack it in again.
It does eat into your time, you may as well write off the whole day when you go gliding, and I mean at this time of year putting the gliders away at 2200 after arriving at 0700. Sometimes you may get a couple of hours soaring in, sometimes you may get a couple of five minute circuits in but that's the deal with gliding, either accept it or don't do it. It is however far more sociable than power flying, although having said that I like being on the winch, take your flask and some butties and chill out between launches....as long as I'm not on for hours at a time.
