Doubles isolator valve hitting head

[galodoido]

I was to able to get enough clearance by using the lowest hole in the backplate, turning the knob slightly to the back, and also adding an extra inch to the shoulder strap. I still hit my head slightly so I may lower the tanks using the straps another inch or so.

I try to get the tanks as low as possible when renting doubles, and with mine, I adjusted the isolator so it's at something like a 45o angle instead of straight vertical. Generally speaking, the lower the better for trim, at least for most people. For me, the ideal position for trim makes it a little harder to reach the iso valve, but I put up with it because I like the trim.

you can drop the tanks in the bands a bit
