Making some progress with the 450x prototype...this setup looks to be excellent. It really is a work of machining art.
If you recall the setup I took to Jimmy's class.
With two squadron lights this setup looks to be at least a couple of pounds lighter than the 8" with roadbook holder.
Awesome layout and clean location for the RAM mounted GPS
276 mounts like it was meant to be there.
I'm going to pound this through 1400 miles of the Tour of Idaho in a few weeks. If it survives that pounding, it's ready for prime time.
