I've always just gone with an SA Mastery Trout on my 9' 5wt for general use. There may be additional lines out there now, but that's something that's not broke, so I see no sense in trying to fix it. If tight-line nymphing, throw on a longer leader or use a purpose built rod for such things as there are far better tools for tight-line/contact/euro nymphing than a 9' 5wt.
