I ran a single disc with std master cylinder all year.........never had a single braking issue caused by over heating or lack of braking power...... AND i finished 3rd overall..........................nurdy nur nur
oh and i did have the fork leg for a second disc...just never felt like i needed it...............
as Ali said go with what you feel confident with other than what " others " say is best.......
