I am not a big weed-wacker line fan. Weed wacker line though is just a nylon variant. I use a thicker stiffer nylon rod that is straight. If you're anal-retentive and won't ever insert a soft patch from the muzzle end, you can still just stick it all the way down and then insert your patch in the eyelet at the chamber end. I however clean from the muzzle end with only soft things so I can't damage the crown on the barrel. I figure keeping any cleaning agents out of the barrel port and getting less of it on the breech o-rings is preferable. Either way, the rigid nylon rod will allow you to clean up or down through any sort of baffle or moderator stack.
