Best hay brand?

Hi guys, I have owned chinchillas for a little over a year now, they are currently on Mazuri pellets but hay wise, I am still going back and forth. I had them on Oxbow Timothy for well over the year I've had them, but lately it's quality had gone down and I don't like it. I switched to Small Pet Selects and it was horrible, very short strands and more dust than hay. What do you guys recommend hay wise for my little guys? They aren't picky, but I am and want them to have good, green long hay...
