First thing I would do is contact Brian Niska at Whistler Flyfishing about the warranty options on that rod since they're the Loop service center for Canada.
You have a few options. One is to learn how to spey cast your single-handed rods and see how you like it first. If that does everything you want, then you're golden. Second is to go with a switch rod like the Loop Blue you're looking at or one of the other brands of switch rods like TFO, Beulah, Echo, etc. Third is to go with one of the smaller two-handed rods like the Beulah 11'6", Echo 11'9", etc.
Where you plan on fishing it is going to be the biggest factor in the way you go. If you call Brian, tell him what you'd like to do with the rod, your skill level and all that and he can give you some good recommendations. I've purchased five rods and matching lines from him (three single handers and two double handers) and every setup has been bang on.
