I'll second the Easton lock on grips, I love them. Before that, I used the ODI Yeti grips. They're a great tacky grip for DH, but not very comfortable without gloves...but I always wear gloves.

Sram lock on DH sillicon grips, just fitted them to the mainstays of my fleet. I've run ODI/lizard skins/sunline/funn grips and not really got on with them, spank spoon and subrosa grips are my other go-to's, nowhere as good as the srams though
Deity knuckleduster is my personal favorite as they are absorbing, amazing grip, and you don't have to wear gloves even with very sweaty hands. If you ride ridged grips then you might not go back. The only disadvantage is the ridges tear easily after you crash.
Revolution Suspension grips with waffle pattern. I was skeptical at first but all it took was a minute down the trail and I was sold! Put them on all my bikes right away and never going back to anything else.
