Rod length doesn't matter much tight-lining, it's more of an action thing. With this in mind, if they'll let you sit on them till they surrender, GO FOR IT. If they're spooky, pitch or swing them and then I love my 7's. If it's pole timber or along a riverbank, then the 10' or 12' will be my weapon of choice. I also like the long rods for using a deep float.
