Ditto to what Bruce said :
Absolute performance the "a" Schempp is a bit better - IF you fit comfortably.
Here in Uvalde Lisa Trotter [who is small] fit fine but cannot reach
things in cockpit - you need to be small but with long arms!
Talked to a Ventus 2bx owner last night who got the 2x version
because it is a longer cockpit [I presume like 2c] and he is 6'6".
It comes down to the designer, Klaus Holighaus made the "a" to fit
himself and the "b" to fit everyone.
Gerhard Waibel's cockpits fit the more "rotund", as do Grob.
LS are in between. Having spent 5 days trying different cusions etc
to get comfortable all I can say is comfort counts, parachutes need
to be picked with the glider in mind as well.

In the "a" model cockp[it and in Jantars you definitely need a
backpack parachute not a Slimpack type. This gets you forward far
enough to reach everything and with only a thin astronaut foam
cushion under you you can be comfortable. My Ventus C is one of 6 or
7 built with the "a" fuselage.
Much the same for larger people in "b" and "c" models even.
The "a" model can be improved if you have short legs. Cut 35mm off
the front of the seatpan and add that half way back after cutting it
in half across the glider.
For really big people who have trouble fitting in with a parachute I
can introduce you to a gentleman who will make you a custom parachute
where the pack forms a headrest. He lives not a kilometer from me.
Former French paratrooper who has done lots of defence parachute work.
For the rest I'll sell you you a nice National Flat backpack.
From what I saw at Cunderdin in early 1979 I think Klaus Holighaus
made the "a" model to fit Brigitte. I was showing them my Mini Nimbus
after the contest and I did say to Klaus that the cockpit was
ridiculously large. Brigitte was nodding energetically in the
background giving him the "I told you so look". Within 12 months a
Mini with an "a" model fuselage was flying (the Lentus) followed soon
after by the "a" model Ventus.
For performance, the wing is the thing. Ron Sanders and I did some
flying with his Discus A TOP and me with the Ventus C A TOP.
Fuselages and tails identical. I was a little heavier at 400 Kg , his
glider with him about 365kg. No problem for me to outclimb him and
then out run.
Lastly for improved comfort, don't have your wallet in your back
pocket. Applies particularly to airline pilots. :-)
