Whatever works best for you Lamar. That 10 pound bottom pour is a nice unit.
I started out using a simple hot pot 4# unit as my lead vessel but used a ladle instead of pouring. I've tried the bottom pour units but didn't care for the nozzle thing underneath and currently have been using 20 pots with ladles to hand pour. I've done it for so long its second nature now. I have a six-ounce ladle for big stuff and a smaller one to handle most of what I do and can hand pour jigs down to 1/80 ounce without any problem at all, and the mold for them is a semi-custom designed for the bottom pour pots. I do around a 1000 1/80 each fall and will have maybe five or six mis-pours in all of that pouring.
