Have tried these stickbaits with some success but i do agree with Brandon that they are difficult to work, but it is not impossible. First time out in choppy conditions i cldn't extract a favourable action, but when i used it next on another trip where the seas were flat i was surprised at the beautiful darting roll it produced. It subsequently nailed 4 GTs and a bluefin before i kept it from being hijacked!
Trick to it is a medium action rod (like for all other stickbaits) and fast but long twitches with enough pause time in between.
Attached a pic of an average specimen just under 15kgs.
