I was gonna say that: if you want the ultimate in canti design you have to go back to wide profiles. Low profile is a compromise in marketing bikes w/ slopping top tubes that look sexy. Since everyone decided brakes should not be on chainstays; a bad decision based on a bad muddy day. Chainstays are stiffer and seatstays should provide comfort, not stiff platforms for brakes. The sum of those fashionable design decisions givs you finicky mushy braking. Solution was Vbrakes and finnaly disc brakes on chainstays.987s for me if you want later designs. Sure M900 look nice but it's the triumph of marketing.
However wide profile ones avoid the compromises with cable pull and highly variable mechanical advantage of low profile cantis. The old M730 wide type therefore take the win for me.
M900 or exage, avid or suntour.. it´s the same bad geometry, bad location.
