Although, i reread it, he does say it lacks trim pockets. My bad
You can put a trim pocket on a camband. Or you can put it on a shoulder strap. Neither stops you from wearing a belt if you find yourself too "top heavy" either.
The downside of having them on shoulder straps is they get in the way when you fiddle with stuff on d-rings and in a back-(inf/p)late you do need to be comfortable riding very low in the water topside. The upside is you can get to them and ditch the weights, you can move them up and down to find your perfect balance spot, and you get better face-down trim esp. towards the end of the dive when Al80 gets light.
You won't know which way you like it better unless you try both.
