i have the severe delirium and its a homerun, the numbers on it are similar to the Columbia disorder, but i can say with confidence that these are not the same IMO
the SD is longer and a bit stronger, great arcing motion, even at OBB surface
I also have the GB2 gold, this is a great piece- i do like the GB2 quite a bit and i wasn't disappointed at all
It seems EBI is turning the corner...
