I have no problem with the line going thru the guides... the problem is the line (with the stop knot) coming off the spool smoothly during the cast.. When using a spinning reel, if the stop knot is wound onto the spool, it will catch as the line is coming off the spool during the cast. The string stops are the worst, because they are always higher than the line. They catch, no matter how close I trim the ends..
