pk is really simplified clf with a bit of tai chi flavour. there is still a ncf clf/tc school in ipoh. you should be able to get some vidoe tapes of contestants using pk in tournaments from those guys. also if you know them well, perhaps a video tape of ncf performing his 3 sets of tc forms and weapons, ncf's tc sword form is very good and is one the best that i have come across so far. good luck sf !
