I was once at a camp fishing for pike when my rod broke. Since I wouldn't be able to service it until we got back into the city, my friend let me borrow his Silver Label 8 wt for several days. Loaded with a 9 wt line, it turned the big flies over with ease and whipped northerns up to 33" pretty quickly. I haven't had the opportunity to replace my rod after it was repaired, but if I do this experience has made me lean very heavily towards the Silver Label.
In addition, I have NEVER had any problems with Orvis customer service. It's great.
