Thanks Guys! Here is my follow up longer video where I compare the #14 to the 70/120 a bit more. Though I had a bit of a calamity, when I was polishing the tank the back brace screw head popped off! I have the remains of the screw drilled out but can't it out. I have order some left-hand drill bits, hopefully I can get it out. Then I need to find a proper screw for the rear brace.
