Late last year I built some 58mm deep carbon tubulars for a local racer that I know -- 24h radial laced in front (DT Comp, heads in), 32h 2x rear with a powertap (DT Champ DS, DT Comp NDS). He had the rims and hubs and all I chose were the spokes. They are generic Chinese rims and I was unable to get a spoke tension spec from the manufacturer so I went with the Zipp standard (100 kgf) for spoke tension.

He describes them as feeling a bit "whippy". He's a big, powerful guy -- goes about 220 lbs and when he's on form has an FTP around 350W.

Based on what I garnered from the link and this thread, there's not much more I can do with the wheelset to make it stiffer for him. If I'd been able to spec the front wheel I think 32h would have been the order of the day. I was a little surprised by how much lateral stiffness was attributed to spoke gauge in the article, but I don't know if going to DT Champs all around would make them perceptibly better for him.
