I personally use Excel but i was thinking of KSC. They make great guns but im not sure about their BB's. Should i get KSC?

Haven't used BIO's myself more than once or twice a few years ago. Cant remember if I noticed a difference. They were excel.

For most guns (read aeg's) i like airsoft elite/infinity .25s. i've found that they are the most accurate/consistent of the major brands (outside of the heavier sniping bb's).
What's a signature?
i've been using the systema ''premium'' bb's rsca gave me with the gun he sold me...so far no problems
