It's proven the new 2011 Super Soaker Hydro Cannon DOES feature CPS tech, but is it as good as OTHER older CPS water cannons like the 2000 model CPS 2700?
SO here's a video.. one thing for sure..they definitely perform differently.. I guess you'll just have to decide which one you think is better for you (that and the CPS 2700 is discontinued!).
Aesthetics also MAY play a part... :P
