I couldn't tell you about the Rio Santo, but I do own a 5wt Imperial. Personally I think that the 6wt would be an ideal rod for streamers and Stillwaters. I use my 5wt imperial for throwing big articulated streamers up and the Madison and local rivers as well as lakes. It gets the job done, but a 6 weight would definitely be an awesome rod for what you're looking to do. I wouldn't consider the Imperial as a true fast action, but it is close as I would put it between medium-fast and fast. I'm also looking into a more streamer and big water 6wt rod, as well as carp and bass, but I'm currently leaning towards a Redington Vapen. Good luck!
