I started fishing the fat gitzit back when they first came out,and started making my own tubes soon after.I use tube lures almost exclusively.I doubt if you can fish them wrong and I have tried most methods of fishing the tube,but most are rigged with the jig as you commented.I use the egg shaped head 1/8 oz most of the time.these are molded on Eagle Claw L571 size 1 LASER SHARP hook.The mold is a Do-it model EGJ-6-A I find that the drop and feel of this head to be just right.Using 6 lb Fireline with a good spinnig rod the feel is excellent. I make my own tubes in a bunch of different sizes 1/16 to one inch in diameter,and use the 5/8 jig head at the heavest.
You also can use a floating jig to foat it behind a sinker set up tipped with a piece of ightcrawler,or a piece of sucker.
