What do you consider “steep”? I sent in an over 15 year old 8124 that two of the 3 sections were broken, only the top section intact. Forty bucks for essentially a new rod.I go through my local fly shop to have them send rods in for repairs. With that said, the pricing for repairs on the older models is steep for a previously "lifetime garuntee."
Since it is all part of one family, maybe they are trying to keep up with Rio, which has got to be the worst fly line website ever.......I think the concern was with Sage's Web site rather than their repair services per se. I haven't accessed the repair pages, but I find using their Web site incredibly frustrating and almost impossible at times. Things take waaay too long to load, and links to other pages aren't activated until the page fully loads, so you click and click and go nowhere.
And welcome to the forum!
