@Dammit
Do you mind sharing some info on the butted tubeset? Particularly at which part that thickness of the tube should be considered the most (I believe at the DT/BB intersection and DT/HT intersection)? To what degree do you think we can save weight on thinner walls (from butted tubes) without affecting bike stiffness? I remember Craig Gaulzetti said that his main skills in frame design is his ability to determine what thickness should be used for a each rider.
I also notice that Zona and Life are the most favourable tubesets for rear triangle. Is it because they do the job better than Spirit throughout? Or is it just to save some cost?

Columbus have a PDF catalog on their site which lists the tube thickness for each of their tubes. You might the numbers interesting.
http://www.columbustubi.com/pdf/tube-sets-2014.pdfI know this is Weightweenies, but I personally would not choose to have the thinnest of tubes (Spirit) if it affects the robustness of the frame. Does anyone have experimentally determined numbers on the difference in weight between a frame made from Spirit and one from Life, Zona, or Cromor? I would guess it is in the few hundreds of grammes range, but an exact number would be nice to know.

DJT21 thanks for the tip. I've been in touch with them a while ago and their prices seem good (and they have a lot of options at different price points). Anyways as I said I'll wait and save more, seems that the 2000e price point will get me what I want (e.g. duell vogue).

There is a frame builder in Washington State that specializes in frames for tall riders. I've seen his work and it is top shelf. I believe the pricing is quite attractive as well. Plus with the good exchange rate, you might score a smok'in deal.
