At some point I'd consider getting a Jett in the 155 for my cyclocross bike. I think I will stick with the 143 for a while, since I won't be putting nearly the miles on that bike that I do my road bike...and during races my butt won't be in the saddle as much, anyhow. If I end up doing a lot of outdoor riding this Winter it may be a nice thing to have on that bike, though.
