Personal preference is for CB’s, much more float, much better clipping action and a much nicer release.
The down sides – bit more maintenance though you can put a bearing rebuild kit through them in 10 mins these days.
The Old stuff that doesn’t apply to the new pedals – they fall off the axle – not any more thats XTR
The plastic cage is slippy – it’s made of metal on the candies
I used the Mallets in combination with a flat style shoe (5-10 minnars) for DH and the tougher AM stuff. Most of the time I’m not with Spec shoes and Candies but that is more to do with my confidence on the pedals rather than anything else.
