I will probably get Bashed for saying this, but out of those, ARROW is my favorite manufacturing company.
I know that most Arrows are incredibly rough, don't age well, and have bad transitions, but think about it. Without Arrow, we probably would not have seen the corkscrew in '75, the tubular steel track in '59, or the Log Flume in the 60s. They were also the first company to send riders over 200ft in the air, or suspend them below the track as well. (Not including the SCs in the early 1900s)
Sure, these things would have shown up eventually, but Arrow was the company that can be credited for pioneering the modern Roller Coaster. (Although Schwarzkopf could put up a good argument with that.)
(BTW, Anton Schwarzkopf Coasters are actually my fav, but it's not up there)
It really made me sad to hear that Arrow went bankrupt, particularly after 1999's Tennessee Tornado, and X at Magic Mountain. They were trying to make a comeback, but, unfortunatly, it was just a little too late.
