I just did my first snagless conversion, and I wanted to thank everyone for warning me about "the burr"! I was able to heat the end caps with hot water and pull them off, rather than push. I could see the protrusion caused by the burr under the cap and avoided it easily. Had I never heard of the burr... >shudder<
Thanks all!
