Mike, I just swapped the old spool back on. Seems I had used the older spool which was supposed to be interchangeable, but the top skirt was not as wide on the one I had problems with. The spare spool that matches exactly has Yozuri Hybrid 20 on it, so will leave it alone. Could be a skirt issue, but will probably rewind onto Shimano AX4000. BTW, the reel I was fishing is Okume Epixor EFS60, the different "spare" spool came from the Okuma Metaloid 60, you know, the one not meant for salt water
