Source for disc mower blades

Looking for a good source for disc mower blades for a 416 new holland. This is the first year running a disc mower (previously only had sickle). I got some from shoup but if you have a better source or have found something you like let me know. I would like to try some flat blades if I can find them. I mow everything from small grains, sudex, millet, mixed native grasses that can vary from very thick to very thin light hay. Thanks
