I ended up going with the Blender Bottle, mainly because of it's solid reputation and a cool white-on-white color I found on their website. That said, people should look into the Spider Bottle and Jaxx Bottle. Both are good blender bottle alternatives. Heard some mixed reviews of the Cyclone, like it leaks and the lid is hard to clean.
For Soylent I really see no need for the blender ball or the spring in the Spider Ball. Like I said, i've had no problems just shaking it, so why have something extra to cleanup or make noise? On that note, I've heard the Spider Bottle does make noise, but significantly less than the Blender Bottle.
