I second armi0024. Bought 50 of the 20gm micros (which feel pretty sweet by the way) and he shipped them all in small flat rate box so shipping was great. They are Zippy brand, not cherrys, but i don't have any problem with the 20gm and they don't make any twangy sounds. The 125gm ones on the otherhand do, but they take a good deal of force so maybe any micro would twang at 125gm.
