I'm with you there Butch... just look at my avitar (profile picture). Those two giants came from Lake Erie... I sometimes wake up in the middle of the night with the memories of those pigs ripping the rod out of my hand in that crystal clear water. There nothing quite like ripping a jerkbait in clear water watching wolf packs of 5-7 lbs smallies chasing it down!
Back to the tube bait for a minute... I like using a light head also, however, when Gobies are present, that oversized head makes a huge difference. They don't really care about the rate of fall as much as they like seeing that fat head. If you give this a try, you'll see what I mean. It can be a little tuff getting the jig head inside the tube, but if you wet the tube first, it's not too bad.
There is a head specifically designed for this purpose called the "Bite-Me Big Dude Goby Head Tube Jig" (You can thank Mark Zona for the name).
As for the Fluke Tail Goby at $0.77 a pack... I hear a bell ringing and a carnivale announcer shouting "winner!". Great find, I'm sure they will go to good use.
