Simon - can you give us some idea on the size of the guides that have been put on? I don't want to rain on your parade with a new rod but relistically, if they're too small, a FG isn't going to help you much at all. Your only option may be to get new guides on it and if you're going to get it changed, you should be hitting up the guy for using guides that are too small now. The other more workable option for you may be to go to a shorter leader and have the connection outside the last guide. This will mean a shorter leader but if you can get it to 4 feet, it should be fine.
