The only reason to not always use wide profile cantis which have so much more mechanical leverage is the unfortunate fact they stick out far, can interfere with panniers if you have racks, and worst of all they might hit your heels if you have large feet and ride a smaller frame size, or they might scratch your legs as you dismount. If you can run wide on both front and back though do it because wide cantis work and feel great. I would call the CX50 medium-profile cantis. Low profile cantis are hell on earth with short-pull brake levers, don't go there, there's isn't enough leverage and your hands will never be strong enough.
