Snuffers are 1 7/16"s diameter and weigh 160g as glue on. They are also stamped steel and vented.
The BigJim's are 1 1/2"s diameter and weigh 250 glue on or 300 screw in. Solid non vented rockwell 50 hardened teflon coated machined steel and everyone spin tested.
Yes the snuffers are very good heads and they are cheap.
Even though the Big Jims are expensive(out of my controll-American quality cost money) they are not as pricey as some and they are Great heads that are very tough and super easy to sharpen.
I have shot 3 deer with these heads out of an 82# bow. I have broken many ribs and glanced of leg bone and ultimatley ended up in the dirt. Wash them off "optional" and two minutes with a file, and back in the quiver razer sharp and waiting for there next victom!
