Thought this was cool.

 

Technically that isn't a stand-up jig head but an upright jig head, there is a big difference. When a jig head is stand up, the hook is up and away from the bottom, an upright jig is exactly what an Arky style jig, like you are showing, does, it keeps the hook facing upright while laying flat on the bottom. That is my favorite head style of all the jig head shapes out there.

my mistake. You're right.
