Bought these for the 2011 Black Diamond Trail Shock Poles but can't figure out how to install them. Do these tips work that those poles, and if so, how do I take off the long flex tips and replace with these? Can't make heads or tails out of limited instructions. This is my first pair of trekking poles. Thanks.
