What company makes the best/most accurate LPI/Micron screens for dry sift

Hey guys,

Basically the title of the post, looking to get some screens to make dry sift with. Currently I am looking at pocono screen supply but debating where else I could get some high quality LPI/Micron accurate screens to use. Not sure what other people recommend or use but figured this would be one of the places to ask. Any input or advise would be greatly greatly appreciated.

i bought a 220mesh screenprinting frame that's worked well for me and keif/trim hash. about a 50micron equavilent. i dont do multiple screen runs, just the one screen

This guy used to have top quality screens for his bags. I cant really speak for his screens but my bags are old from 2004 and have had a lot of use and are still ok to go. his reputation is solid imho.
