With bad Sticky Shed tapes the sound can drop off within seconds of the tape 
start, but you got  almost perfect play of a complete C60. Any shedding 
problems with these particular cassettes are probably pretty minor. If 
you're in the mid Northern hemisphere and just coming out of winter, just 
leaving these possibly problem tapes till mid year and transferrring them 
after say a week of hot, dry weather may be enough to make them perfectly 
playable. No special baking needed. Just a thought.

Best wishes,
Tim
