Mixing cat litter?

[cat owner again]

The cat litter I like is fairly expensive. Costco has some cheaper litter but it just has so much dust when it is moved. Does anyone mix two litters with success at clumping? They are two different sizes and consistencies.

I mix these two with great success:

I have found a good combo with about 2/3 World's Best Cat and 1/3 of Fresh Results the Walmart knockoff of Nature's Miracle.

I like World's best because there is no dust and it lasts a long time but it is more costly so that is why I would like to mix. I tried it with Costco and not so great. Costco clumping works well but it has so much dust. I don't like cleaning it and I can imagine the cats breathing all that in.

I put a little bit of clumping in at the bottom to help trap urine, with the majority of the litter being larger non-clumping clay. One of my medium-haired cats doesn't really crouch, but simply sits down to do his business. Clumping litter ends up sticking to him in all sorts of nasty ways.

I had to mix litters for awhile when the cats and I moved from Canada to the United States because the type I had before isn't sold here. It didn't seem to make any difference for how well it clumped, even though the grains were significantly different sizes.
