I ordered the xbulls. I could not afford the maxtracs. However....I did do some research and like the youtube referenced above there are others youtubes comparing the different brands. Some brands just snapped in half.. However there was one video that sold me on it. A guy in austrailia.. It started out as a guy comparing xbulls to max trac and I beleive he thought it was gonna be a slam video against x bulls.
He torture tested them side by side in all kinds of situations...and in the beginning he had the attitude of ....well these wont hold up...but slowly that attitude went away. In the video you see each test...its not just talk.
by the end of the video he and 2 buddies are sitting around and saying that the x bulls are great....almost became an x bull commercial...he did see some fatigue..but no cracks...he thought....long term...who knows how they will last.
But I thought to myself...if he could trash those like that..they will work for me.
