Hi Brian. Brand new to this forum. Hope I'm not too late. I also have your exact setup...Ranger and HP steel 120's. Only difference, I use a LOT (32 to be exact) more weight than you. To balance myself, I have about 1/3 of my total weight in the tank trim pockets and the rest up front. I played around in a pool to try and get the right distribution. I could probably fine tune it more, but a lot also depends on whether I am wearing my wetsuit or dry suit. Hope that helps...4 months later.
