yeah that is a beast but I can guarantee you this, chop with both and see how much more energy you have after the 1311 to tilt beers <img src="/ubbthreads/images/graemlins/thumbup.gif" alt="" /> you'll agree with me then
Dunno, I'm sure it will be lighter, but I don't get that fatigued from my zilla and I've used it before for extended periods of time clearing back the overgrowth from the road over at my parents place
The Zilla is bad [censored], I really wish I still had mine, alot has to do with the edge on them as well, yours looks fully convexed and no V-bevel blade is going to outdo a zero edge. I just look at my thin machetes and they are so much better at chopping that the typical heave blades. Horn Dog should chime in here, would be interested to hear his opinion.
