Today I picked up over 50 7" reels of used tape (I actually recorded on them back in the 70's and 80's - they were recorded once, and played back about 20 times each mostly on a Teac 3340 as I remember). THey are predominantly Scotch 207, with some 203 and a couple of 150's along with two rolls of Maxell UD90. Any problems with sticky shed for these tapes? The price was right, so I can chuck them if there are problems. Thanks, Larry
