Buying a CO2 Bottle Soon

[SilverBullet]

I am buying a Pure Energy 9 oz or 16 oz CO2 bottle soon.

All I need to know is:
Are 16 oz bottles much heavier than 9 oz bottles?

I know you get a lot more shots out of a 16 oz, but I'd rather have mobility than a 16 oz tank.

mobility is fine with a 16 oz. i have one and also, its not heavy at all

Thanks. I'll stop asking questions about tank sizes and sh1t, and buy that 16 oz already!
