IMOHO there should be no fires. The differences between modern Campy and Shimano are now minor as I see it. Having a brand preference is a personal thing and cannot be justified by any kind of technical or quality superiority between the brands. I'm getting Ultergra 10 speed on my custom Tetra Pro. I would just as well be satisfied with the equivalent in Campy. I would have insisted on Campy due to the better (in my opinion) brake hood ergonomics but the new Shimano brake hoods have changed and are now so similar to the Campy hoods that it is a wash.
