Drilling realistic fighting applications vs. T/B/F rolling chi sau or bong-laap looping drills are 2 very different things.
While everything has it's place, if one focuses a large portion of their training on the latter, they will then assume this is realistic fighting and post up clips of it, title them 'gor sau' and then post them on forums as proof of fighting skills, when in reality it's just development execises.
Exactly. Yet this is mostly what is shown in the clips that are being talked about that are titled 'gor sau', as Wayfaring has has pointed out.
Most people assume 'Gor sau' means more than just drilling. 'Specially when the clips are of a lineage's top guy trashing his students to cool fight music and are being pumped up as example of his fighting prowess. Not saying the people in the clip can/can't fight or don't have skill, but let's call it what it really is: High speed drilling of looping tan/bong/fook push/pull chi sau & bong laap drills to really cool fight music by people of unequal skills and low resistance levels
Which brought me to my original point: this is the downside of spending so much of one's traing time on these types of drills (like T/B/F chi sau) in. They only represent a very small timeframe in a fight, and will lead one to lose sight of what it is to fight against a resisting opponent that doesn't play these same game or even present the opportunity for this very specific timeframe.
