Just wondering if anyone here has replaced the tips on their BD hiking poles..... I had a broken tip following the last hike on my BD Carbon-cork poles, ordered some "Flex-Tips", and just replaced the broken tip.... instructions said to soak the tip assembly in boiling water for 2 minutes, then remove the old tip, using pliers if necessary. Well I had a bit of a time getting the broken tip off the pole, used some channel lock pliers and it finally worked loose. Installed the new flex- tip fine. But I cannot get the 2nd tip replaced, the old tip just will not come off. I'm afraid to clamp down too hard with pliers on the carbon pole, maybe break it or gouge it bad. Just wondering if there's any tricks to doing this I'm not seeing..... tia
