The thing I've noticed about paper leader is that it's most likely candidate for a bad splice point.
Why? Do not know but I theorize the paper absorbs and dissipates whatever makes the glue stick to
it. On the other hand, paper is proven to not mess up the tape around it over time. I think if
you're relying on ANY old tape where it's a huge issue what leader medium is used, you need to come
up with a plan, today, to transfer that material to digital media and/or create safety copies on
newer tape. The simple fact is that tape is not forever.
