BTW to get back on topic, here's a video of the "WT" lap sau drill as shown by Alex Richter out of NYC. It's more linear and uses a front punch rather than a back-fist. It also avoids laying two hands on one as per the kuit "Yat fook yee mo yee fook yat". Since it uses a fook or jut rather than a committed lap, some schools prefer calling this repeating sequence "jut-chuen-da" rather than "lap-sau".
