I have an old Orvis golden eagle glass 8wt that is a casting machine. Unfortunately it weighs in at a whopping 7.5 oz. I like to use it but never for a full day, It's much too heavy.
When I fish the salt I like to use a 10 wt. It powers a cast out into the wind much better than a lighter rod. But even the slight weight difference between a 9 and 10wt is very noticable. When i use the 10wt I wear an elastic wrist brace, with the 9wt I do not.
