The C has excellent large dive brakes that produce a steep
over-the-trees descent to the start of your short field,
but I suspect you are right that the flaps of the B provide
a slightly lower energy landing.

The B trailing edge divebrakes create more drag than conventional
divebrakes, plus increase the effective flap angle. This allows one to
maintain a 50 knot or so approach speed at up to a 45 degree angle of
descent. Done right, it's more like landing an HP than a conventional
flapped glider.
