I never liked the fact that they changed everything so frequently and that they shoved shit on us without testing it properly (bio pace, STI, u-brakes...). Added to which suntour is just plain cool, likewise campa and any us exotic stuff - none of it works as well as shimano but that's not the point, these are retro bikes after all.
Like the build and i agree trying something other than Shimano , i have put Cane Creek brakes on my Proflex X-works . But your brake system looks like a work of art , great stuff .
