Hey Kidnova how are you.

I agree that if you can afford it go woth a full system which will eliminate any slop you have. As stated, an add on should tighten things up however you need to determin where your slop is coming from. It's not going to repair bad gimble bearings or pins, stretched cables etc. if funds are limited, I would first repair anything needed inthe gimble itself, then go for the twin rams and last but not least the helm. At 70 plus you are going to need it all. Stay safe
