Question: I've thrown about 10 Bosses and I've not encountered any that were as stable as an Xcal. In a headwind this weekend the Boss was touchy...it definetely wanted to flip a decent amount. I think a stable run or an X version would be appreciated for big arms and wind(it makes the Xcal seem so slow...).
Right now, the domey Bosses are the more stable. If you don't get one with a "poppy top" then it will fly more like a Wraith than an XCaliber. The flatter the dome, the more touchy and flippy it will be.
