Recently we have been discussing moving to all BIo bbs for our OPs here in Northeast Pa. Our Field is already using all BIO and we are trying to move other Fields to do the same as well. (Think Green

We are suggesting that people go to G&G BIO bbs, both for .20 and .25 that we use. I have seen all kind of comments concerning what BIO bbs are the best. Airsoft Elite and Madbull are two mentioned so far. I use the G&G brand which I have put 1000's of rds through my M249 and various Custom M14's and I have seen nothing but GOOD reviews on them.
I am looking for some input from other people. I would like to hear some good arguements for one brand or another and what you use personally.
