Default bicycle seat post?

If it were me, solid metal. Tubing is to save cost and weight.
solid steel.

Overseas - in the Marshall Islands - we had Goose neck steering and
high seats. It was great on the back and such. Sadly they, the high handlebars
and high seats are not allowed in the states.

Some extremes were inverted frames and weird stuff - nothing to do, just dream and do.

I have a friend who is about 6'5" tall and weighs maybe 240 pounds, a big

called me
last night with a problem. His bicycle seat post - raised way up due to his
height - is bending on him. He bought a replacement and it too is
bending. He
asked me to consider designing and fabricating him a suitable replacement.

Of course, for a piece maybe 18" long the cost of the material isn't
going to
bankrupt anyone. I was thinking chrome-moly tubing if I can find it in the
right diameter, and forging a swaged-down neck area. He is thinking solid
bar of aluminum. Minimum weight and cost with maximum strength is the
design
goal. (A google for some exotic turnkey solution has quickly ruled out
such due
to really high cost - I had no idea you could spend $200 plus on a
bicycle seat
post!)

Anyone "been there, done that" or have any good ideas or input?

Thanks,
