Mine personally are: AK-47 Redline | MW AWP Medusa | FT M4A1-S Decimator | FT USP-S Cyrex | FN Karambit Marble Fade | FT AK-47 | Bloodsport Five-SeveN | Violent Daimyo Desert Eagle | Naga What are your favorite skins?
My personal favorite skin that I am using currently has to be the UMP Exposure, I think MW or FT. It's a pretty good looking skin for the money it costs. Also, the M4A1-S Hyper Beast FN is my favorite looking skin that I do not own.
