Takahiro is sponsored by Lucky Craft, in articles I have read about the Classic they mentioned the fact that he was using the Bagley even though he isn't sponsored by them. Lucky Craft responded and said it doesn't mind their pros using other baits in order to win. As they see it, use what is necessary.
I fished a Tour event last year and I was surprised to find the pros I fished with caught their fish on one thing but then when they reached the stage, the said a totally different bait, one made by their sponsors.
I talked to one of them about that and he said some sponsors are very strict about another company's baits. He even said some even show up at tournaments and go through tackle boxes as sort of a surprise inspection and depending on the pros contract with the company, violators are disciplined accordingly.
This sounds a little extreme to me, I wish more corporations were like Lucky Craft, do what needs to be done to get the win, but the competition out there for sponsorships is tough and I guess some pros will do what they have to, to pay the bills
Now if Tak was using a custom bait instead of a Bagley, maybe he didn't mention it to keep it as a secret weapon for the next tourney.
But I'm sure if he did us it; H&T would like him to own up to it.
