i don't use feints. if i throw something out there, it's either going to connect to the target, smash through an attempted block, push your hands out of the way, sucessfully get blocked or redirected or whatever.
i like working in combinations and having each aspect of the combination full power.
being my size (5'7", 150ish lbs), i can't afford to give opponents the time to get any advantage so i constantly use the big guns, so to speak.
