The nylon weight belt should work for shallow dives, but when you learn to go deeper, you'll want a rubber belt that will constrict as you go deeper and things start to compress.

Where the weight goes is really dependant on your bouyancy and trim. Ye definately want it symetrical on the belt. In scuba classes we tell the students to start with 10% of your body weight and we take extra weight with us to adjust. Scuba has a lot more bouyancy factors. I'm 6-4 220lbs. I use 10lbs scuba diving, but freediving in 15' of water I use 16lbs with a 5mm suit. A full chest of air and I'm extremely bouyant. Hopefully as I learn more I can get the amount of weight down. Salt water you have to add about 5lbs too.
