Keep the spey rod. They are no problem in a driftboat.
Here's how I set mine up. Since these pics I have added a second row beneeth the rod butt holders for an offset. I can run five spey rods on the left side. Two on the right below the enachor. That's a lot of rods and more than you need but 3 is quite comfortable.
Swirtch rods live in between two worlds, they are no good in either, just stuck in the middle. But if you have to have one Gloomis makes a nice switcher for the money. I reccomend call in Bob Meiser (he is kind of the inventor) and having him send you one to try out. Odds are you won't like them. I had him send me a couple 2 years ago...he also sent me a 11'7" spey with them. I bought the 117.
Anyhow. Snowed in and sharing my dubious opinions...as always.
