Sounds like you picked up some wee warts. They're great plugs if you get some that swim right. I've found them to be a bit@h to tune. i personally prefer the regular sized wiggle warts but in low clear flows wee warts are good and I like the chrome/black best. I would recommend a swivel off the belly and put the siwash on that. I think you'll find it has less of a negative impact on the action of your plug. Make sure to add a little scent and you should be in business.
