Generally speaking its because of their limited supply and their retail price of $25. They usually have stamps that look nice on a wall so collectors will snatch them up.
As far as their flight, they do stay straighter longer and have more overstable finish but they don't have a lot of glide. Most of the Champion rocs made from 2003 on were pretty like this. The SB rocs, 2001 CE, and 2002 CE rocs have different flight paths but you can find discs that almost do the same thing without having to pay e-bay prices. Personally, I really like the glow champion because they aremore flat topped and more overstable. But if I lose the one I have I may just give up and throw a z-wasp.
Well they surely are rare. After finding 1000+ discs in lakes I have never seen one. I did find an 8X roc once as well as a Super Roc from some tourny in Iowa. I'm sure people around here throw them, but no one I've ever played with threw one.
it's because they are overstable and most people are torque monkeys that can't throw stable mids/putters so they seek out overstable plastic versions of stable discs in order to compensate for their lack of form.
I just picked up one of these last week. The Played Again here got in some x-out 2006 champ rocs and I was trading in some discs and I decided to see what the fuss was about. I got to say "Eh," It is a good disc but I don't really have a lot of use for it, I never really need the overstablity it offers since where I play we never really get giant winds. It is good for forehand flicks and rollers but so is a new DX roc. I give it a 7/10.
I have never thrown the old CE ones though so I can't really comment on them.
My buddy and I headed out to play in the middle of the night last night. There is a local course that has lights on, all night. It's only a nine hole but it is the coolest thing to be able to golf anytime of day or night.
I didn't have my golf bag but my friend has hundreds discs. After checking out what he had, we negotiated a deal for his unused 2004 CE Glow Roc.
This thing is awesome!!! It's overstable like a baby monster or something. It has some serious teeth. Needless to say, I wont be using it for my straight shots, unless there is a very tough wind. But, when I want to finish left, throw a flex shot, or get some good skip out of a mid-range, the CE Glow Roc is like nothing else.
yeah you can try to convert a torque monkey good luck. I usually get,
Torque Monkey: "I throw my Z pred almost as far as you throw those beat up avengers so why should I throw something else?"
What do you throw in a headwind?
Torque Monkey: "Z Extreme what else? oh and I sometimes carry a new max weight Z crush for when I want a turn, but its not very consistant, too flippy?"
Z Pred-ESP Cyclone-Z Force-Z Aftershock-Z Comet-Ion-Pro Rhyno
best at holding an overstable line was the 01 ce roc.
most overstable was the poppy top domey 11x kc roc.
one thing i know: any ce roc released after the 2001's were very squirrely when compared to DX/KC rocs. the Super Roc re-releases are like that also. needless to say, wtf would anyone want a squirrely roc?
Predictable 50' well defined S-curves (when compared to firebird, monster, ect.) and it fills the same roll as a new 11k KC Roc, just 10' shorter and will stay overstable for a while. My 2006 Climo Glow Roc is just getting to the point where it is like a brand new DX Flat top only used for a few weeks.
