The zilla's handle isn't well suited to a proper kukri swing. The LTC has more of a flare, so you can give it a good wrist snap, but as mag said it's not needed.
For the sake of fair comparisons, I used the same basic swing and grip on all the different knives. The LTC would chop even better if I used a kukri-style grip utilizing the butt. Even swung like a normal knife, it still bested everything else on the list.
Too bad SYKCO can't make a LTC type Khukri. It would be affordable and high performance. Either SR77 or SR101 would be just fine. For those that want the most impressive Busse, get the KZ. For those that want performance for an affordable price, get the SYKCO. It would be great.
