In reply to Jedi1969:
I did some research into this recently as I needed to buy a pair (they make a huge difference, especially with a heavy pack).
The general consensus from reading lots of reviews is:
- avoid ‘twist-lock’ models as they eventually fail, and go for a pinch lock mechanism
- avoid ‘suspension’, it is a gimmick that doesn’t make much difference and is another thing to go wrong.
- horizontal (perpendicular) grips feel nice on the shop floor but get annoying on the trail; better to stick with regular vertical grips
- cork grips feel nice and some people swear by them.
