I have owned a Strykezone 380 for less than a week. I have never owned an Excaliber, but would like to someday. The Strykezone is much narrower when cocked (and when uncocked). I DO know THAT much about the differences. But I would STILL love to own a crossbow that I could restring without having to have a bowpress, like the above poster said. Each one has their merits. I am getting extremely good accuracy from my 380. Killed a deer with it sat morn. (It's the thread in this sub forum that no one has responded to) The land I hunt is brushy and not simple open woods all the time. So a compact bow is a blessing. And the 380 is compact and lightweight. (6.9 pounds). They have fixed the limb issues from 2011. When shooting from a ground blind, you don't want your limbs to bump something when you fire the bow. This is less likey to happen with a narrower bow. The stryker is 13 inches axle to axle. Pretty narrow. But I don't know how narrow the Excaliber is, other than I would LOVE to own one someday if I see the need for TWO x bows. Good luck in your choice. I'm NOT brand loyal. I was just giving you my perspective and I hope it helps. kevin (I'm pretty sure the Strykezone has a lifetime warranty)
