Newer TT stuff may be better, but I'm not satisfied with the stiffness of any of the Nitto, Syntace, or Profile bullhorns I've ridden. Agreed that nashbar etc... are much worse. From an engineering standpoint given comparable material and manufacturing quality it's just a matter of how long of a 6061 or 7075 tube you have pointing out into space, and for a bullhorn it's always going to be longer than for the hoods of a drop bar. Down in the drops is a different story of course, but unless you get super deep drop horns and a tiny stem the bullhorn position is much more comparable to the hoods.
