I heard that Switch Chucker was good for nymphing since the handling section can help you mend better.
Another line that is good for switch rod is the Royal Wulff Ambush, the taper design is close to Airflo Rage compact, and they come with just the heads and complete full lines.
However, if you thinking about dry fly presentation, you might want to consider Scandi type heads. I have the same spey rod as Vagabond, Beulah Platinum 5wt 11'7" Spey, I am using Beulah Elixir V2 300 switch version with and 10ft versileader for it. Really good for touch and go cast and will do sustained anchor casts as well. Unlike Scandi heads; the Ambush is not Air Jordan. It will turn over the fly rather quickly.
The new SA Switch Adapt is pretty similar to Ambush, with bit longer belly than the Ambush which probably will give you better loop stability and won't turn over as quickly as the Ambush.
Please note that I am still learning how to 2H myself and at times still getting that smack in the back of the head for being too fast and too aggressive with my casting, so don't sue me over the above opinion.
