All good advice - I would just go for grooved discs and not have the drilled option, there have been examples of the discs cracking. I ran them before and didnt have an issue myself but found the holes clogged up with dust so now just opt for grooves.
I have used Black Diamond and Tarox discs previously with no complaints - obviously there are varying costs involved dependant on brand - Alcon etc
What is your budget?
