Large rubber mallet, anyone? ChristieLites packs one with every truss pin kit. Never really had an issue?
I'm not familiar with Global Truss' version, but the pin truss I've used has the top and bottom pins facing each other. Not too terrible to knock out, though the lower ones can sometimes be a pain. However, I used an in-house truss system on the west coast that had the pins coming in from 45 degrees to each corner. THAT was a PITA. Having to hammer upwards was bad enough; having to rotate 60' of truss was worse.
Checking the truss with the pin type is easier than bolt-together as well; you can quickly run along the truss line and verify the clevis pin is installed, whereas bolt-together requires checking every bolt with tools.
