That is what he and I use now on our KH24". Total looser tire. When I find something that hits the spot I'll let you know. I'm going to start testing other tires myself.
I think maybe some people have developed crooked riding habits as a result of gazzaloddi? And then when turning to the duro tire, find that they are somehow riding in circles without meaning to... Mine has tracked perfectly straight since day 1, it just took me time to learn how to actually turn into uphill slopes at first, but then I couldn't ride any uni very well at that stage. The 24x3 tires all seem to be nearly identical from looking at them, it seems pretty amazing to me that they can yet be so different in riding practice. I think since I know the knobs are just going to wear off, I will probably continue selecting tires based firstly on price, and then on how it rides, and how cool it looks :-)
The gazz has an almost square profile so if you're on a skinny or angled rocks or whatever you can get total traction even if only a small edge of the tire is in contact. Also the sidewall on the gazz makes it wayy better for hopping IMO.
If you want a lightweight 24x3" tyre your options are pretty limited. The Gazzaloddi weighs about the same as the Duro, if not more and the IRC Kujo is only 40g less than the Gazz. It seems if you want a 24 x 3" tyre its going to weigh lots because of all the rubber there. Maybe get a Dyno fireball.
