Right not I own a mini and I love it but it can't really keep up with the high end markers I play against all the time.
TCambs, What problems are you experiencing keeping up with highend guns? What type of FPS and ROF (BPS) limits are you playing with usually? Really ask yourself what do you find about the Mini is giving you trouble?
Is there a setting on the gun, that the Mini can't do for tourney play?
How is the Mini failing you?
