Taking your title to the thread (best single engine glider) very literally, probably one of these two:
Lange Aviation - Antares 20E - Intro
ASH 30 Mi
Both about 60:1 I believe.
And to the folks talking about a low aerotow launch failure, a low winch launch failure is also horribly entertaining for the few seconds it takes to get back on the ground.
