I don't really know much about this, so I have a a question. If you have to use a heavier weight line (e.g., a 6 weight line on a 5 weight rod) so that fast rod will perform better, isn't what you really have done is transform the fast rod into a slower action rod--which maybe a lot of us would find better to start with? Or am I missing something (as I often do)? Just asking......
