I noted with some alarm I now have 19 Craves so took them to the field for a Crave off. Three throws each BH and one throw sidearm.
Results were ...
"Old" Neutron Craves ... pre-Hokom I assume. have two of these in the 170's. These definitely turn more than any other Craves I own. These also feel a little more "chunky" in the hand. That could be my imagination, but the other Craves all feel flatter.
R2 Neutron Craves ... picked up three of these with recent PDGA renewals that the owners didn't want. These are pretty fresh, but they turn a little and give a nice baby S flight.
Cosmic Neutron Craves ... two of these ... they seem board flat and very straight.
Proton Craves ... two of these. They don't turn and fade very predictably. They fly very much like my Clashes.
Plasma Craves ... two of these ... just straight with baby fade. Possibly a little turn.
Fission Craves ... two of these ... hint of turn, very straight, seem to go a little further than any other Craves.
Hokom Craves ... six of these ... all over the place. Some are OS, some turn and fade. Not sure why the inconsistency. Probably the archer and not the arrow.
Sidearm sees a bit more turn than BH ... IF ... I hit the release angle right. Then they fly like a Sarah Hokom sidearm and it's lovely. But my sidearm is a work in progress and not the most reliable yet.
Interesting results. I wonder if you just got a freak run of patent pending Craves. All but 1 PP Crave I've thrown have been Teebird like. I can get them to turn, but thrown flat they are straight to fade. I have several Hokoms that are somewhat all over the place, but none as stable as my PP Craves. I have 2 of the newest Plasma Craves, and these fly closest to the PP Craves. Straight with a bit of fade.
But in my experience, the stability of MVP discs is much more to do with the run than the plastic. I have tons of Envies for instance, and while one of my Eclipse Envies is my most stable, another Eclipse Envy is my least stable, and that's including Electron.
