the only sources that i buy from are ones that i know big time competitors are using. Conduct research on who seems to be liking what, what reviews and ect. If i see a guy thats on the forum thats been on longer then I have and looks like shit, and swears by a product and no one else is vouching it i lean away from it. All the local gear where I live is bunk, I dont trust any gear dealers at all. I know half of them recrimp there shit and draw some gear out and replace it with olive oil.
