I just noticed that the ISTD and Laird techniques differ on the point of closing as opposed to half-closing on the cha-cha-cha chasse (the simple sideways one). I also noticed the ISTD stipulate that the first step is a small step which is different from what I was taught - there is no mention of this in Laird.
So I just wondered if people have views on which is preferable and if anyone had insight with regards how (ie for what reasons) the technique has diverged.
