Exactly my point, Jason. You draw it up, then turn it over to the shop guys, and reap the beautiful rewards. Pro results. That's the advantage that most don't have.

I actually did have such accesses in my past. And made a career out of electrical work and design. That's how I know professional results when I see them.

Enjoy the fruits of your labors. Very nice! You might be interested in Looming your cables to your mount and equipment. I use a product commonly referred to as Spiral Wrap. (Tricks of the trade. )
