I have a couple that I use. I like a wool one with a light coat of preservitive oil. This is the last pass down the bore before storage. I use some cotton ones to sop the bore with solvent, but I think they likely don't put any more solvent down than a patch. They also get filthy dirty and need cleaned out after using them. On top of all that it takes a lot more solvent to get them wet, I won't be replacing them. For either use I think wool is superior, it doesnt hold as much liquid, but still coats well. I especially like them for the slug barrel though, I never feel like I get anything close to a tight patch otherwise. I'm way too concerned about cleaning (by my own admission) but its calming to me.
