No problem, I'm going probably going back to Lasham to have another go at a weeks course again next year (they start in April), the instructors I met (Peter & Darcy) were excellent. Lasham also has a simple but natty simulator which is good for teaching cable break recoveries.
To be honest, once you've flown powered a/c, gliders are straightforward, they do hone your rudderwork though and there are a few oddities, such as speeding up to land!! (Eh? says the power pilot) and the scary 'First time on the winch launch' experience. Overall, I think it's a worthwhile thing for any power pilot to do, even if you only aim to go solo locally as I wanted to do.
As you are in Winchester, you are more local than me and it only took me an hour to get there. May even see you there. (Might even join just to fly-hire the Cub!!!).
Be seeing you....
