LS-6 and rudder size

I've been looking at the LS-6 gliders lately and noticed that on the
LS-6C the rudder looks almost twice as big at the root chord than on
the LS-6A. Is this an optical illusion, or is it real?

I am guessing that since the later version of the LS-6 had tip
extensions, the rudder was resized to allow for that.

Would love to hear from any LS-6 drivers of the "smaller" rudder
versions how the bird handles, especially regarding rudder inputs.

Regards,
Brad
