Assuming** (I hate to assume), you are wearing neoprene. Probably 7mm. With a hood and gloves, I'm guessing you would probably need around 20lbs. A stainless backplate is 6. 100cuft tank is 1 lbs empty (Faber). Regs 4 lbs. Weighted sta is another 6. Plus cam bands 1. That's 18 lbs alone. Now throw a reel and flashlight and you are real close to the 20 number. Again this is just a guess you would have to do a proper weight check. But you could always dive a Worthington for the extra 2 lbs negative over a Faber. Then you are diving a balanced rig, and you are not over weight. (your mileage may vary, please do a weight check.) No sense in buying weight pouches if you don't need them.
