Optimize and I live close together, we used different companies to ship but had similar costs. Hot shot does not ship painted frames and may not be available at the time you need yours because it's economical to ship with multiple kits. It's a dude with an open trailer and a normal truck.
I shipped mine with Stewart Transport (they do factory five) and have an enclosed semi trailer and can ship painted frames.
Stewart is substantially more expensive than hot shot unless you bundle a lot more people like I did. They also take forever, too and the driver was a rude piece of **** to me.
