It looks like the Cibola GB mod basically turns the Cibola into a Vaquero. Add a GB knob and threshold based AM to a Cibola and you have a Vaquero, right? So if a Cibola is really good, a Vaquero should be great! If you like ED-120 and you have ED-180 couldn't you just turn the disc up a bit and have ED-120? ... or am I missing something?
