Columbus do a seat tube which is butted at the bottom but has a long length of thicker butting at the top, it's about 750 long. It would be on the thin side as it's just 1mm wall for the top section but as you're not a big rider, I think it would be enough and would save you a lot of weight
ah nice i hadnt seen that. Although i wanted to go really large dia on all the tubing, so 34.9 seat tube. Im not too fussed about weight i dont think itll be crazy heavy, just not particuarly light
