Prototype I in I-blend plastic - 175g blue/purple

Plastic & feel: Pretty standard I-blend, overall pretty quick to break in but has held onto a bit of stability even after getting scuffed up off tree hits. Rim depth seems slightly more than the Maya/Mamba and Tern and feels better for someone that throws Emperor/Pharaohs.

Flight/usability: I tested this over a few rounds as a long turning driver that functioned as something a little easier to get up to speed than a Shryke but longer distance than my Roadrunners. For my BH the LSS definitely held the turn for a long while but the glide kept it in the air. Attempting FH, I found Proto I to be a bit touchy and didn't handle full power throws flat without rolling over too quick. I definitely see a place to use this out of windy conditions and shaping longer lines in the woods with its turn and fade characteristics providing pretty good control.

Comparable discs: I don't throw too many discs in this speed/stability range. Generally lighter weight Destroyers and my normal Shryke/Falcon/Pharaohs which are a speed and stability tick up. Could see this being more like the Discmania DD (new) or Discraft Thrasher - especially if it gets produced in a more premium blend plastic (C/Halo S-blend).

Its a 12 speed, so not for beginners. Its very straight to flippy with reliable fade at the end. Glides for DAYS. Like if a Hades was a good mold. I reccomend if you like flip up 12 speeds at sea level. 

Throwing at elevation 6000ft, stable and nice flight very similar to a stable Pharoah but maybe not as much glide. I throw Pharoah and Maya regularly, but an Emperor when wind kicks up and this wouldn't get bagged at all. It's a nice feel, but not really understable or useful for me, it definitely flew straight when I forced it, and had plenty of glide consistently going around 40ft past the other two prototypes, just not enough different from the already brilliant Infinite drivers I have.

Of the 3 new prototypes that Infinite dropped recently, This one was the one I was least interested in because it didn't seem like it filled any gap in Infinite's lineup. Heck the initial flight numbers for this mold are basically the same as the Sultan. Despite that, I still purchased it because I wanted to try all 3 of the prototypes and this disc actually left a very good impression on me.

First, I want to state that this disc feels more like an 11 speed than a 12 speed. I even compared it to other 11 speeds I have such as Wraiths, Traces, and DD1s and the rim width feels the same. At most, you could probably consider this an 11.5 speed. But I think this being an 11 speed is actually a positive because that would make it different from the Sultan and fill that gap between the Czar and the Maya.

I live in the Columbia Basin in Eastern Washington, and our elevation is somewhere around 400 to 500 ft above sea level. As such, this disc flies fairly close to its turn and fade numbers and maybe even a little more understable. It's a certified bomber for my beginner noodle arm and can take the role of a beat in Wraith without needing to beat in an actual Wraith.

I still like the other 2 prototypes better, but this one is still worthy of being put into full production. I like it a lot. You can call it the Vizier or something like that lol.

I threw the Emperor a lot when I lived in Florida and loved it.  After moving to Colorado and throwing about 6500' in elevation, the Emperor can sometimes be a little stable for my arm (380 average drive).  I bag the Maya at elevation for a hyzer flip driver but it is not as trustworthy in the wind.  So I was excited to try this prototype as something in-between the Emperor and Maya.  Did some field work with it yesterday and I love it.  Lots of glide, the right stability for my arm speed at elevation.  Was throwing it just over 400' consistently in a flat field.  If I was at sea level again I would go back to the Emperor as a flat thrower and use this as a good hyzer flip option.  At 6500' thrown flat this prototype has a little turn and then a consistent slight fade at the end of the flight - even into a slight headwind.  
My flight ratings are based on 6500' elevation.  I think at sea level likely the 12,6,-2,2 are accurate numbers.
