One thing I'd like to add FWIW

On my 6.0, I did away with the bungee uphaul- it always puts tension against the downhaul, etc.
Instead, I put a line and a seperate cleat on the side of the tiller arm. That way, they would drag in the water and still give you some control, and pulling on the line and cleating it kept it up when it needed to be up.

I also would get the lock down thingy (forget it's name), about 1-2 inches from lock down, cleat the line in, then lock it the rest of the way down.
This technique always kept it from 'backing off a bit' when it was locked down.
