I would guess you do not have much experience/knowledge
of the LAK 12. It is not 'a bear to rig', just very
heavy like all gliders of it's type; the cockpit is
in fact small, both in length and height, and it is
not as wide as it looks due to the intrusion of the
undercarriage and flap rods. Anybody who reaches the
max cockpit load is likely to be very uncomfortable.
It also has no facility for tailballast.

In answer to john's original question; look at say
std cirrus or nimbus 2. Iwould think the limiting issue
is likely to be maximum cockpit load rather than your
height or other dimension
