No, I have Terrabites on her since almost new! I an going to get a spare set for other terrain than normal. I am just looking around and doing normal research. The Ocelot scored well in testing, but only 6ply bias tires.
On a 500 id run them but take a look at the load rating a few of the smaller tires load rating . Kinda right on the edge for a 700 or 1000. Unless you were running the 26s on the 700 and 27s on the 1000. Could probably get away with 26s on the 1000. Depending on what your doing with it.
Mine were the BigHorn knockoffs, and i thought they did well for the money. Probably the worst aspect was that they weren't going to wear as well as genuine BH's...but then again, most tires dont.
The same tire will be available under numerous brands,so you might find it cheaper elsewhere. Just depends on if they are on sale. Check RMATV as well.
