UPS, IME, is a lot safer than Fedex. When I received my Skyline Glaub back in febuary, via Fedex, there was a 3" diameter hole on one side the the neck.
It looked like either a forklift stabbed the box or someone put their foot through it, a mere 3-4" from the neck of the bass, which was in a gig bag. That one had me sweating while opening the box.
Never had a problem with UPS, and I'll only ship using it. That one time with Fedex was enough!
