Longest GB? OG Helix Dogbone Designs GB.
Worst GB? My own pre-order for the Cruciformer. It hasn’t been that bad really, I just expected people to deliver on time and I’m stuck trying to explain to people that the parts that are out of my hands. . . .are out of my hands. my money is stuck in the GB until I ship most of the orders, I want to finish it, etc. I can promise, the worst GBs are the one that you run since it can harder on the GB runner than the participants.
