Saveloy,
If we spoke to any FIS / RIS then forget anyone else getting a word in, as we constantly search for better lift and our position over the ground constantly changes depending on basic direction for next turning point as well as potential lift patterns!
I strongly advise you to pop into your nearest gliding club on a sunny day, and get your butt in a decent plastic 2 seater with a good driver in the back and go and have some serious fun.
You just cant beat a quick 300km triangle flight, dumping water ballast @ over 100kts 5ft off the deck on your return to the airfield, then retiring to the bar and reliving the whole flight in detail, about how daring and darstedly you evaded death from a 152 bimbling along in your way.
