What's a "light brigade version"? I agree about multiple sizes! I was thinking that, but I forgot to put it in my original post. I would probably buy 2 of the KZTT if I had the choice out of 4 different sizes (with the original KZTT being the largest). The blade needs to be thinned on the KZTT design, according to all the reports, but that's easy to do.

Light Brigade is a two part treatment, you remove the handle leaving a 'webbing' of metal that's thinner than the stock thickness, like an I-beam. It has three effects, it lightens the handle, it reduces vibration compared to a complete skeletonization, and it creates a structure that is stronger and stiffer for it's weight than a flat peice of bar stock. The same is true of an I-Beam. If an I beam weighs 1 ton, it will be stronger and stiffer than a piece of flat stock of the same width utiliing the same amount of metal.... I think...
The second part of the treatment is to the blade grind. Normally it's like the thicker version, the thinner version is the light brigade version. The hollow grind is thinner and lighter than the convex version creating a much better cutting geometry for slicing and chopping as long as it's not on overly bindy material like wood splitting or hard plastics.
In the case of a LB TTKZ I'd hope that the light brigade treatment would only be applied to the handle. By lightening the blade you'd end up neutralizing the benefits of lightening the handle. By having a blade heavy balance you can use a smaller blade for the same work of a heavier neutral balanced blade. Or you can have a more effective chopper in the same amount of space at a few ounces of weight savings.
If the LB treatment was applied to the TTKZ or KZII blade I'd hope that it would be in the form of a traditional wide fuller. You lighten the weight but don't increase binding like you do with hollow grinds.
