The Inca is a solid option to fill the stable/overstable midrange slot in your bag.  It feels and flies very much like a Roc3.  Higher power throws produce a straight flight with a late fade.  I don't think the fade is the 3 posted on the website and I think it's closer to a 2.  The Inca also seems to have a little extra glide and I can almost get the same distance as some of my fairway drivers.  I've only thrown the Inca in MF Glow C-Blend (one of my favorite plastics) so I can't speak to other plastics.  The Inca is a solid midrange and a great addition to the Infinite Discs lineup!

I got an x out metal flake glow Inca with a double stamp. I threw it 4 times in a round on our clubs home course. iT IS NOT what the flight numbers suggest. It doesnt handle power well and it does not fade. Hyzer flips and rides right at bit. 
 

worst advertized numbers. Even with double stamp it is not stable. My chariots and tombs had more finish. It is a joke. Do not buy it unless you want a straight fighter when there is no wind. 
 

5/4/-2/.5 dont buy this. (Coming from a guy who throws only infinite molds)
