The PIK could be set down on a dime once the technique was learned.

Every airplane can be set down on a dime once the technique has been
learned (and is regularly practised!). Of course it may be more
difficult for some planes than for others.

I'd have to agree but perhaps not all. A long wing ship I've heard about
that really doesn't spot land is the U2 (it was just hangar talk - can
anyone comment?)

when you the desired point was reached, you simply dumped the flaps and
flared for a 2 pointer.

Just smashing down the glider doesn't count. At least it doesn't at the
spot landing contests of our club. On the other hand, when outlanding,
the only thing which counts is the result and nobody will care about
style, of course.

This wasn't a smash down. Rather it resulted in a particularly smooth,
precise, and satisfying landing (once one learned to eliminate the PIOsfrom
cranking with one hand while controlling pitch with the other). Problem was
that the technique was not documented as far as I know. Just the technique
taught by one experienced PIK owner to another.

Otherwise I would submit that gliders that depend on flaps only for glide
path control *cannot* be consistently and safely landed 'on a dime' in the
normal range of conditions without the kind of non-standard technique
described above. The PIK couldn't and the Schweizer 1-35 couldn't in my
experience. And I think that fact that no one builds production gliders
with this configuration is a reflection of this. But my experience is
limited here.
