line for cues
it looks like the label says No.9 = 9 threads= 27 lbs. test. #9 cortland was used years ago on many cues. white with specks(black/green/blue) was a common line used on cues. 18 thread woiuld be 54 lbs. test and would probably/possibly be unacceptable for cues unless a "fat" wrap is wanted.
