The biggest I got was 4.7 on it. It has a tight swimming action to it. Its a ROF 3, the rattle in it isn't vary loud so it doesn't scare the fish. I mainly using it in stained water the larger profile helps alot and rattles are always good. But the fins on it did rip off in 4 days of throwing it, I have been looking for replacements for them but have not found any.
