Jason:
Can you also explain the options with buyng this mold? I am not a tube user or maker so I don't know what the difference would be if I get the mold with t-rig or mold with tube insert or the other options. I get if I have a spline I don't need another but that is where it ends!!!
Little help for the "tube-challenged" guy here!!!!

Hi Jim,
The difference is the thickness of the head. The Texas Rig version has a little over 1/2" of meat in the head, the Tube jig has around 1/4" thick head (you slide the weighted tube jig in the tube and want it as far forward as possible). The only thing that determines which it is, is the insert. The spline and mold are the same. You can get both (the inserts are $6) and then your mold can make them both ways.
The T-Rig obviously is preferable (at least to me) around heavy vegetation and timber. Because of the exposed hook on a tube jig I only use this when fishing deep water without a lot of cover.
I mainly fish them T-Rig, but most the guys up North have been buying them with the Tube Jig insert (or both). When I pour them for T-Rig fishing I like to pour them in soft or a medium soft plastic and treat them as a 1 bait - 1 fish lure. I just put the sharp part of the hook in the hollow part of the tube and let her rip when I get bit.
It's very interesting where the tube molds mainly get sold. Obviously in the North / North East, but there is a pocket in the South and West that also fishes them. I don't know a lot of people around here that fish them except for Spring, but they are effective year around. If they aren't popular in your part of the country I would say that is an extra reason to fish them. Tubes catch fish and are very versatile and weed proof. I would say the biggest challenge with a tube is learning all the different effective presentations.
