A great addition to the Millennium lineup.  The Falcon has some stability and the glide to cover some serious distance.  The extra stability makes for an excellent compliment to a Shryke.  

Decent high speed straight flying driver. More stable than I expected. I max out around 400 feet for reference. With the 100 or so throws that I gave it I was able to get some nice long distance drives, but I couldn't get it much farther than my wraiths, which are much more controllable. I prefer the Innova Corvette over the falcon personally, as far as my highest speed driver goes. A nice stable Corvette is more workable for me and has more glide. I would say if you want a shryke with more stability the falcon fits that bill. Just not ideal for maximum distance in my experience

Talk about a BOMBER, pop top swirly falcons are Hyzer flip machines! 

Great disc!  If you're looking for a faster disc, the Falcon is a true straight flyer with a little fade.

I picked up a max weight white pop top and I really enjoy it! Very similar to a Star Destroyer depending on your skill level but for those that can bomb will notice it goes farther. Out of the box it is not flippy in a headwind but I can't speak for once the plastic breaks in. I recommend a flatter lower weight for those who throw sub 400 ft and a nice stiff pop top for the big arms

Disc: Millennium Sirius Falcon 175g, white, Run 1.1 

Feel: Flatter flight plate with slight dome. Sirius plastic provides standard grip (slick when new but breaks in) with good durability as the tradeoff. The Sirius  Run 1.1 are slightly stiff new.

Rim depth is slightly shallower than other 12-13 speed discs like the Destroyer/DD3 but quite a big difference between the Falcon and Scorpius/XCalibur/PD2 exists. Rim width is between Quasar/Boss 13 speed and Scorpius/Destroyer/DD3 12 speed which is comfortable for both forehand and backhand grips I use. 

Flight: Consistent, max distance driver for backhand throws. For my arm speed (max distance ~400 ft), the Falcon remains nearly straight in calm conditions. Slight hyzer releases will mitigate slight headwind concerns and provide a flip to flat flightpath with a stable finish. Anhyzer releases hold for a while but always seems to level out without turning into a roller. Clean forehand throws on hyzer reach flat without turning over and then fade for a stable finish. Less ground action than the Scorpius typically has.

Comparisons: More comfortable rim depth than the Discmania DDx (Glow C-Line 175g) with less abrupt fade and a similar flight speed. Faster & more stable than the Innova Tern (Champion ~170g). More glide & less overstability than the Star Destroyer & Sirius Scorpius. Step down in stability from the S-Line DD3 with a little more forward glide and less finish to the fade. Somewhat like the Standard Scorpius after a couple rounds (more durable plastic though).

My current lineup of distance drivers (overstable to understable) :

Sirius Scorpius (runs 1.8/1.9) / S-Line DD3 (first stock run) / Sirius Falcon (run 1.1) / Standard Falcon (first run)

Impressions 

Versatile enough for both backhand distance drives and forehand torque, the Falcon is a fun distance driver which provides stability & glide while being comfortable & flat.

Rumored to be a Scorpius top/Shryke bottom & core mashup, the Falcon in Standard and Sirius plastics cover the middle (slightly overstable to understable) section of the distance driver stability spectrum. 

Upper division players should be able to maximize the Falcon's flight capabilities best. 

This thing has SO MUCH glide. I don’t have quite the arm speed for a max weight but a 169g flies pretty dang straight but I don’t advise throwing into a headwind over  8-10mph or else it’ll turn right over.
