Seatpost setback

OK, I'm trying to start a bit of an ad hoc database on seatposts
(without wading through catalogues (usually uninformative)and talking
to sales staff (ditto, sometimes) that can get all you tall guys with
long femurs (you know who you are) in the right possie on 74 deg.
seat-tube bikes (I don't want to reignite the KOPS debate, but humour
me, please?). Ergo, what's your favourite/most horrific experience with
LONG setback seatposts (20mm+ horizontal behind seat-tube centreline),
any diameter, any length, any clamp style (beyond pressed steel/swaged
tube)?

I'm 5'10" (not tall) but the seat-tube angle on the Pug
is fairly steep so I run a set-back post. I think it's 75deg
but I could never find the manufacturer's geometry specs
for this frame to verify.
What details do you need? All I can remember is that it's
an American Classic alu post (black). It's maybe 40mm
from centre of the post to the rear of the set-back clamp.
Not sure of the diam. but could check (prob 27.2).
Clamp style: Two allen bolts, one locks fore/aft, one is
for the vertical angle I think. Harder to explain than
adjust! ;-)

Thanks in advance. I'll try and think of a suitable recompense for
people not motivated by sheer desire to share their experiences for the
good of cyclingkind. A week in the Bahamas? A copy of the Suntour
programme from 1967? Hmm.

This is for tall riders with long legs, right? I need a more
accurate measure of seat-tube angle than me + protractor!

This has some interesting snippets:
