That's great that you got what you were looking for. I am surprised that your local friendly Sage dealer didn't get a Demo from his Sage rep for you to try out. The fact that they didn't try to make that sale should be discouraging.
As for stocking every rod...no one, not even Bob Marriot's stocks every rod. Sage makes alot of rods, stocking every one would mean that they couldn't carry any other brands. Sage would love that, but the consumer would shop else where.
One cast can change your day...maybe your life.
