I use my 11' 7WT switch rod that I built for big river smallies a fair amount of time.
I've had mixed results with the switch rod and am not thrilled with it. It may be that I have not matched it well with the line. I can't remember the line, but I cut and shortened the head trying to match the grain weight with the rod. It may also be that I have not mastered the two handed stroke with this set-up. Most of the time, I'm confident that my regular 7WT allows me to reach further when double hauled. This is especially true with poppers. I don't like the switch rod when anticipating surface game.
With that said, the length of the switch rod makes it great for swinging streamers and even better for high stick nymphing. Put a big buggy helgrammitte nymph under a big strike indicator....this rod roll casts such a rig effortlessly and the length really allows you to get a good drift. If, like me, you do a lot of drifting big bass flies under big indicators, a switch rod is deadly.
It's also pretty good for early season trout fishing if you're fishing nymphs and streamers on big brawling water. I think the long, two hand grip system also makes the rod somewhat less fatiguing to handle than a regular rod of the same length.
Anyway, congrats on your new toys. Give 'em a try and let us know how you made out.
