I like the longer lengths myself. I use my boat hook to grab my release cables.
The reason there are so many Ruger upgrades is because they're necessary.
No need to have to use a hook or have to lean way out to get to your clip either. Buy the easy to install ball/clip retriever. They slide up and down your cable and have a nylon cord that you pull on and press into the cinch to get your ball and clip right to the boat. Very simple to use. Built by Scotty I believe.
It really depends where on your boat they will be mounted if on or near the back of the boat 30" arms are plenty long. But the farther forward you go the longer they should be because it will take less of a turn for the cables to end up under the boat and in the prop especially if your in a strong current. I peronally like scotty riggers for thier flat top which allows me to lean onto it while reaching out over it.
