So, what's 'old school' about weight belts on the Spectre? Sure, the weights come in a belt, but those soft weights transfer from the belt to the integrated weight pockets on my BCD with no problem. At the end of the day, the weights transfer out of my BCD and back into the pockets on the belt. Soft weights are soft weights regardless of how one packs them around. The empty weight belt stows very nicely in the dive station during dive ops.
The positive side of having your rental gear at your dive station on the boat when you arrive is simply not having to lug heavy tanks and weights. The only weights I want to mess with packing are my ankle weights.
