I sold my Sage on Ebay last year. When everything was perfect, yes it was a cannon. But everything is not perfect, and you do not always need a cannon. My deciding moment in selling the rod was my inability to make a short cast and a difficult mend to a 20+" brown on the Delaware. He was junk eating and for over a half hour I tried but could not get the proper control to drift a fly over his nose. He was only 20-25 feet away, but in a very difficult lie. The next time I fished the Delaware I brought my winston Ibis 4 wt and was able to see the difference in control. I sold my sage, bought a 5 wt IBIS. I found that the medium action suits my casting style a lot better.
I also fished a friends G2 Scott last year on the gunpowder. I am thinking of replacing my 4wt with that. Very soft tip, but a lot of power in the middle of the rod.
The suggestions to try a rod are excellent, but also don't be afraid to ask for advice in making your selection.
While I do not own any Orvis rods, I have experienced their superb customer service, and that is worth considering.
