There is a huge difference in stability in this mold. I have a 171 silver GL with a small dome that is less stable than a valkyrie. I also have a 171 yellow opto that is very domey and is similar to a wraith.
I got the chance last sun to really try out the flow at cascade gateway one disc tourney. It flips in a headwind. Other than that its very controllable. Hyzers straight and anny. Hard to putt with tho. I regularly out threw my regular distances. By up to 60ft or so. Has a place in my bag. Prob replacing my avenger ss.
It is definitely understable, but not like a roadrunner or sidewinder. It turns over for me like a tuned wraith. Since it is higher speed (speed 11) it takes descent power to make it turn at high speed.
The extra glide is also noticeable, best seen when the disc is coming out of high speed turn and transitioning into the slow speed fade...there is a little extra carry at this point.
I have found the disc to be most useful when throwing a stand up hyzer...released with a little hyzer, flip-up to flat and then glide. Sweet.
Still waiting to completely tune in the disc, but so far a hit.
BIG shout out to latitude 64 plastic, the quality of plastic and the apparent filling of voids in other flight lines. I have a river, halo, xxx, and flow in the bag now
