i wouldnt recommend using clips or snap swivels with mepps they seem to hook up on the blade on occasional casts which ruins your retrieve try tyin a mepp onto a 60cm piece of line attachted to a barrel swivel then tied onto your mainline does the biz for me
dont tie it directly to you line. Tie the line to some swiveling clip and then put the mepps on the clip. The back end of the clip will spin with the mepps but the end tied to the line wont.
