Buy the LAK-12 if it's performance you're after.

My biggest concern with any glider is two-fold:
1) Will I fit in? I'm 6'3 and fairly wide.
2) Will it handle my weight? I'm 250 pounds. Granted, I'm slowly
dropping my weight, aiming for 220 pounds. Still, that's the top end
of a lot of ships.

I fit nicely in a Blanik L-33 (well, a bit tight on shoulders, and 1/2
inch of headroom before I bang the canopy); and no parachute. But for
my first bird (if I can ever afford one), I'd like to have a bit
better legs for cross-country.
