The size and feel of this grip makes it a winner in my eyes. I prefer a larger grip as my left hand is knackered from multiple breaks. This grip is very durable too, I didn't need to replace them at all last season.
If the grip was slightly softer, it'll damper more vibration and make it more comfortable for the all day epics, but then you'd lose some of that durability.
My new bike came with a set of ODI Cross Trainer grips, they will be swapped out with the Rogue asap.
