Sig Riser.
But... that's so close to the Gentle Lady and the GP Spirit... might as well be recommending the Gentle Lady.
There is a VERY good reason these models get the most recommendations as beginner's sailplanes... For over 20 years the Gentle Lady has been one of the best beginner's gliders you could get. compare the outlines of the Riser, Spirit and Gentle Lady... essentially the same planforms. The Spirit's airfoil is better for speed than the Gentle Lady's. Its been so long since I built my Riser... I can't remember how its airfoil compares... I think its between the Gentle Lady and the Spirit.
Dynaflite also makes a 2 meter kit that is comparable... and its not a bad kit. (I can't remember its name... it looks about the same as the Sig Riser.)
