Apart from the very sweet looking 17.6 m tips and tail ballast what are
the
other differences between the Ventus B and the Ventus C.

The C has a different root fairing which improves performance and handling
at slow speeds. The trailing edge divebrakes are replaced by conventional
spoilers, which makes it a lot easier to properly seal the flaps.

Does the C have the same long cockpit as the B ?

There are actually C/A and C/B variants. The C/B has the same cockpit as
the B, whereas the C/A has the shorter, narrower cockpit of the A. CMs and
CTs use the C/B fuselage.

I believe the C handles a lot better.

Having owned a B and flown a C a few times, I'd say that, at best, the C
handles slightly better than the B. The C is a bit more stable in the roll
axis (particularly at thermalling speeds), and requires less control force
in roll. Ptich and yaw stability are pretty much the same. The C is
probably easier to land for the uninitiated, but can't match the Bs
outstanding short field landing capability.
