Funny you should ask this as I'm actually taking delivery later this very day (Monday) of a Mint Green Sub Ray 4. I've been um-ing and ah-ing over these for a while now and after watching a bunch of Youtube demos and reading up on various reviews, decided to bite the bullet. As others have said, the weight comes in at around 8.9 lbs (4.04kg). My full-fat Stingray5 is around 11 lbs so, personally, I don't expect the SUB to be too much of a problem.
