Grey Ghosts seem to be more desirable. Colin preferred the ghost, he said so many times. He doesnt think 2 pump arms are neccesary although they certainly keep you from being able to rotate the pump assembly so I dont see a reason why not to have 2 pump arms unless your undercocking.
vintagerex.com has basically all the info. Less spirits were made by a good amount so maybe in many years, once most of the guns have surfaced spirits will be the one people are looking for.
Carter doesnt have the only daystar ever, just the only daystar public MCB knows about ever
Spirit or Ghost debate is a pretty old one, id say. Ive only owned spirits so far, and so i guess Il root for the home team, but thats what everyone does.
