I've never used any paper leader personally, but I'm not real crazy about the plastic stuff that seems like the only thing currently available. It seems to do a great job in some instances such as for a dividers that are visible in the tape pack on our TP releases but for beginning and end leader, it drives me nuts! I do have a number of old tapes that have paper leader and I think I might prefer it. I guess the main objection I have to the plastic (Emtec or Quantegy) that I have is the static. One of the reasons I use leader tape is to eliminate the handling and keep the recorded sections of the tape's exposure to the dust filled air for any more time than it takes to play it. I can't help thinking that the static charge on the 2 feet of leader (which can also make handling it a bugger) that I'm attaching to my tapes, is conducting that charge onto the tape I'm trying to protect. There are some archival issues with plastic tape too but there seems to be some disagreement on that.
Well, I've found a source for paper leader so I'd like to see if anyone has had, or heard of any problems with it. I'd also like to know if any of you would like to buy some too. You see, it's very cheap ( $10 per roll 1/4") but the minimum order is 5 rolls. Oh,.. did I forget to mention,.. a roll contains 1000 feet! Actually, it just sounds like a lot. Most rolls of plastic leader comes on 800-1000 ft rolls and I used up one in about 2 years of tape collecting. Unless someone comes up with a good reason not to, I'll be buying 5 rolls pretty soon so if you'd like to try some, PM me
