I had a pair of the Gazaloddi Dual's on my bike. I didn't really like them for the trails in my area. The knobbies were plenty big enough, but the tire has a very square profile, and it handled kind wierd. I switched to a tire with a rounder profile and liked it much better.
Of course, I wasn't riding the type of terrain the tires were intended for. So, there you go! Serves me right!
