I assume Tom is referring to the fact tungsten jigs are measured by width instead of weight and lead jigs are measured by weight.
What ever design the jig is I would like to see it be balanced so that it hangs perfectly horizontal. I think most of us that ice fish know that panfish can be super picky in winter and many times if the jig is tilted any away from horizontal at all they want nothing to do with it.
The way most of us combat this is by tying a tight knot to hold the jig how we want it. It would be real nice to not have to real up and adjust the position after a missed fish or just toss it back down the hole after a catch instead of adjusting again.
