Re: Guide size help for a 2/3wt 12'0''
That will work just fine, but not at all necessary. Ask yourself why it has to has so many guide sizes, it for sure will not aid in the casting all they are for is just to hold the line, and the smoother the transistion the better the line retrieves instead of having to step up and up and up.
It is rod building and 10 different builders will have 10 different ways to do it. I do it that way because I have found with the many builds that I have done it has become the most efficient for me. I especially like the idea of the reduces weight on the upper 2 sections so as not the make the rod somewhat tip heavy also.
