You'd probably want a bit more in the rudder- The 5985's are GREAT on all other surfaces, But I think you might stall it (5985) on the rudder. I have a 5955tg on my rudder, and will be running one on my Suk that I will be receiving tomorrow- I think it's like 20 or 30 bucks more than the 5985, so if you're buying new, would just get the 5955tg on the rudder- you shouldn't be unhappy about the choice- KM
