@ahcalde try moving the backplate holes first. You position tanks *singles or doubles* as low as you can with the height set by your ability to reach the valves, not for balance. You deal with trim in other ways, but for trim in doubles I've never heard of someone wishing they were more head heavy.
yes lossen the nuts and turn the isolater section till it is out of the way. That way you can leave your tank positoning where it works the best. The only other option I see, and it is conditional, is that if you are using tall valves replace then with shorter valves. there is perhaps 1/2 to an inch difference in the neck of the valve body. I will give you links if you want to see both versions if you would like. The primary valves you need to get to is the individual tank valves. If you lower the tanks so that the cross over is out of the way you risk lowering the right and left valve operators out of reach to some degree. Your flexibility comes into play at this point. The down side of turning the isolator valve is that,,, if you are going into an overhead,, the valve may hit the overhead where it would clear more if turned towards your head.How do I do that? Do I just loosen up the two nuts on the side and the isolator loosens up?
