Not as good as prior generation
The current generation of Mallet 3's dont have the grip and holding power as the previous version. I find myself inadvertently coming up clipped when I never had the issue with the previous model. In all I think that the Crank Brothers system is superior to the SPD design because there are more exit options.
I think the new downhill pedals look like winners because they are much closer to the last generation design, I wish I had held off a couple more months and got the downhill pedal.
