Why not turn the old one down to size, then try and put in my own flutes (not too deep of course). I'll see how this goes, maybe when I end up with a useless bit of aluminium that was once a seatpost, I'll get back to you...
Cheers,
At least you could melt it down and make some Coke cans....

No bothers - let me know if you need it. Had a fluted actually, but munga snapped it up. I actually have another fluted one, but its in use - sorry....
