Sorry I have been busy.
NightShift Orcs came in RED, BLUE, TEAL and YELLOW. Though there are some yellow out there that are actually mistamped Pro Orcs. If you bought a yellow one from a Pro player out of the Michigan/Wisconsin region around that time and its yellow, yours may be a Pro Orc. NS Orcs were opaque. 100%. No other Champion disc was, so they were easy to spot and some leaked out to random dealers from all over. A friend of mine was at a head shop in Iowa City and got 2 out of thier bins. They had no idea they were even different, he did and scooped them up. Those were the first I seen, a Red and a Yellow, and I have them both. I think RED is by far the rarest of all. I have seen one other that I can recall.
IMO, they are one of the better plastic mixs, and those were not "stabilized", they were actually more overstable than standard Champion Orcs. That was one of the big things about them at the time, you could crush them, even on anny and they would hold forever. I have heard only a few hundred up to 5-or 600 total released. I guess it would factor on run size during that timeframe. If I remember correctly, I dont think the higher ups were pleased that these discs were made, but I guess Dave could weigh in there.
The Tulsa Orcs were good discs, but neither the plastic or flight didnt match up for me. The plastic was better than average, as I had some 11x KC Teebirds that were in the same plastic that were sick. They still float around occasionally and are noticably different than other 11x KCs.
Yeah, Star plastic is loosely based on the Night Shift plastic from the first batch of Orcs more so than the Tulsas, at least thats what I thought, could also be based on some of the CE plastic as well. I have several Champion stamped -Star proto discs, but I dont think it was totally decided those would become thier own line, I think it was going to be a second option within Champion plastic. Once it came to play though, I think the costs made it move up in price, thus becoming its own line of plastic, more or less. Im sure Dave could also explain that better than I did as I only remember so much.
Original NightShift plastic is softer, and feels aged when its new. If you are familiar with some of the middle runs of softer CE plastic, the plastic that was more pastel and when used got a leathery feel to it, thats original nightshift, more or less.
I have several and really could care less about selling them, which is why they carry a high pricetag. With all the differnt Orcs out there now, I dont think they are worth buying to throw, but they do have a pretty important history when it comes to where we are now. ...and they are the best Orcs ever.
