I have a few customers who insist on LePro tips. I hate installing them due to the low yield of usable tips. I've found the best method is to look for smooth backs but that doesn't always work. If you guess wrong, you have to cut it off and start over. For some strange reason, I purchased a box of LePro's from Atlas a few months back and almost all of the tips have been keepers. Just lucky or better QA?
