I believe the 369mm belt is universal for all the models you mentioned + the 511. The 511 is equipped with the reinforced belts you mention and they have never failed on me or contributed to other breakage. The left center pulley (the rear belt) on my 511 has been changed twice in 2 years due to wear, thats it. All the other pulleys still work fine. Adjust your slipper accordingly and you should not see drivetrain failure (cept for spur gears every now and then).
