Just finished testing my rudder today. I was kinda disappointed with the results when I did attack and stamina testing. But I've actually found some pretty decent use for defense on 5-60/9-60 high needle and 5-60 hexa. Still gets destroyed sometimes against shark on point but it's good enough at defending. As for glide I'd actually say it's slightly better than ball and is better than orb, db, gb and hexa surprisingly. It's just scary to use because it moves around a lot at the start, but if it's able to stay calm then it's a very rewarding bit.
