ASW20 or LS6

I owned an ASW 20F for some years which was ballasted to the aft C of G
limit ( the trim system isn't the greatest piece of design and forward C
of G just makes it worse) and it was a very docile forgiving glider. As
stated earlier the flap system is still the best ever devised which is
very comforting for field landings.
Having said that on the type discussion group Yahoo site there were
numerous posts suggesting that the later B and C models with the blown
wing are not as forgiving, although I have not flown either so can't
confirm if this is true.

I'm under the opposite impression! I found it very forgiving. My
personal experience is 1500 hours in an ASW 20C and never a stall, spin,
or even an incipient spin that wasn't intentional. That's with the CG
about 75% of the range.

The 20 is very sensitive to the leading edge radius of the outer wing
panels.
When I refinished the 20 of my club I made the leading edge a little
sharper - the 20 gained A LOT performance (suddenly it could keep up
with the latest LS-6 and outran the ASW-27 at speeds over 100 kts),
but got significantly less forgiving if it was stalled with flap
setting 4.

I'd say that each 20 flies a little different - the 20 is incredibly
sensitive to the slightest airfoil variation.

Two years ago I flew a 20C that was incredibly docile - I coluld
easily thermal it at 41 kts with flaps 4 - the 20 of my club would
have already spun at that speed...
