Anyone out there(in here?)using or have used the 8"XTR disc's or 8"Saint's(even better-a comparison)?I currently run the XTR 6"er's on a XC bike and am planning on building up more of an all-mountain light freeride playbike so I thought since I already like and have an extra set of XTR dual-control levers I would run either 8" XTR or Saint brakes.Any relevant(yes,I LIKE the shifters)feedback would be greatly appreciated. Thanks,Thomas
