I have been using an A-Series Scott flyrod for two years now (my first flyrod). This is a lower end $$ rod and I has a moderate to fast action. (9wt. rod & line). With the intermediate line that I use I get the sense that it is not loading the rod very well. I really feel the load when I switch to my 350 grain sink tip line. So my question is would it make sense to switch to a 10wt. intermediate line to better help load the rod? Does action of the rod factor in?
