look at the difference in fab. quality...
The quality of the fabrication is the real story. Sorry.
Prettier maybe, lighter debatable. I know Alex uses a very thin outer ss to keep weight to a minimum, its more difficult to keep it looking 'nice' as its as thin as paper - but it only needs to be thin to do the job.

Fair enough. Perhaps when Andy gets a chance, he can post the weights of both pipes, the UKR and the Tams one. They are not the exact same size, (obviously

) but a rough comparison would be helpful - especially if the UKR is lighter in spite of being bigger...
