Hi there, iv tried this technique b4 but not with live yakka though, I just used a pilly on a set of gangs under a float then when the squid attack it and eating away i would cast at it and get his friend, i would say the yakka would be a better option as its live and would kick and attract the squid better. but when there is no yakka's the humble pilly will do an alright job at it.
Cheers
