Awesome, congrats and thanks for sharing.
Have to admit the rails for the new system look awkward, but obviously there is a big benefit, especially to operators, with the hinged system. Im guessing its just a matter of what you're used to...interested to hear OP's thoughts on this.
Are the dimensions of the actual PF/cabinet the same as a Williams wide body? With the narrow back box, does it give you more visible area?
