I'll never understand why Innova saw fit to mess with the Beast in the first place.
It's a tale of three discs. Four if you consider the Starfire and Starfire L different discs.
The Beast was out in I think '03 and it was the new hotness since all anybody could do with their Valks was cry and complain that they weren't CE anymore. That summer Innova had a new CFR-only disc out, which was a weird marketing thing but anyway...that disc was the Starfire. The Starfire was more overstable than the Beast and they fit next to each other in the line-up.
The next year they came out with the Orc. I'm not sure what the Orc was supposed to be, but it turned out to overlap the Beast with a pretty similar flight. There really was no reason to keep both, and the Orc was (any guess?) the new hotness. So they decided to do something to the Beast.
Remember that the Starfire is still there on the OS side of the Beast/Orc, so the logical thing was to retool the Beast over to the less-stable side. With a little tweak to take out some of the fade, you would have a disc with about the same HSS flight and less fade in the LSS end. Sounds good, right? It also almost exactly describes how the Starfire L flies. :|
The Monster was already there on the super beefy side of the Starfire, so about all you could do to the Beast to make it have a unique flight at that speed was make it super flippy. So super flippy it became.
Right away I was unhappy. I could throw the old mold Beast. The Orc had a dumpier fade and didn't glide as well as the original Beast. It was going to cost me 15'-20' if I had to throw it.
I didn't have to throw it, though. The people who got stuck there were people who insisted on throwing Champ plastic. The DX Beasts were old mold for a long time after the other plastics were switched, so you could throw those. I opted for the Pro Starfire, which was maybe a tick flippier but pretty close with less fade.
Also the Wraith came out. The Wraith erased any perceived mishandling of the Beast. It was new hotness x10. So after a bit it wasn't that big of a deal that the Beast had been retooled because everyone was throwing a Wraith anyway.
In retrospect I get what they were doing, but I wish it was the Orc that had been retooled. Old mold Beast>Orc.
