It's all personal preferance when it comes to wheel design. What looks good to one, might not to another.
22 is like said above, on the heavier side for"16's. I'd say if it's under 20 pounds, then you're alright. I'm getting some "16's reall soon here that only weigh 14.5 pounds per wheel, now that's pretty light!
