"wide or reasonably wide drag bucket
low drag
high angle of attack before stall
docile - smooth stall characteristics - I don't want a sharp cut off at high AofA "

That sounds like what modern TD sailplanes are looking for. My first thought would be an MH32 with a loading of 10 ozs/ft**2. Don't monkey with the LE. The stall is fine and it has a good drag bucket at RE for a 8-12" root chord.
