What others have probably already said about the Beadless CFR s line gremlins, and I have every chance I get when a GM / Gremlin thread pops up. They rule, and they should really get another run of them made up to send out into the world, or Hyzer Bomb or Infinite discs can grab on to the mold and present it as a new midrange. CFR beadless are pretty flat. and it's like the Innova star plastic from the pre-number era. The beaded I have is a bit more overstable, and is a different star plastic that is slightly translucent and a bit harder than the beadless star plastic which is opaque and from what I have come up with only available in white.
The beaded is slightly more overstable than the beadless, and really seems like a gator bottom got mixed up with a Discmania anhyzer top. The beadless is stable to slightly over. Both love being thrown hard, and will go pretty far and they also can be used to putt with.
What you have is an s-line.
