Another vote for the SZD 55 here - love mine, also over the discus I've flown at my club before. Super light wings, assembles almost by itself with automatic rudder connections. You just need one more guy and a wing stand an thats it. Self locking main wheel adds to safety, you will never experience a belly landing due to not sufficient locking force on the handle. Has a lot of room and a nice seating position. Buy a used one and you will not see a loss of money if you treat it well, speaking of treatment: older T35 gelcoat lives long if you give it the right care.
