The knots are slipping.I know that Rio sells good products. This is a recently bought 100 yd guide spool. I have another spool of 30yd 4x Rio that i've had no problems with. I'm at aloss as to what's wrong with it but I think I'll take Sagefisher's solution and toss it. At first I thought I was not tying my knots correctly,
Thanks for your replies.
