Noel:

I have bought 3 gliders in the last 3 years. And I can tell you from
experience that one thing that needs to be at the absolute top of the
list when considering buying a glider is - Comfort.

I bought an ASW-15B which is a wonderful glider. It flies great,
thermals well and overall a terrific glider. But I had to sell it
primarily because I was two inches too tall for it. I then bought a
Standard Cirrus which has a couple inches more legroom. Now I can fly
all day long without getting cramped up. It really really makes a
difference being able to stretch out and relax during a 4-5 hour
flight.

Cockpit comfort is essential. If you ain't comfortable in it, then it
isn't worth buying it.

Hope this helps,

Scott
