So for me a "not so young anymore" player with 330feet max distance that want´s to try a lower weight disc. . .should i try a Fission or a "normal" Wave in the mid 150s?
Fission only comes in three molds: Volt, Tesla, and Photon.
Fission = Neutron with the addition of micro-bubbles.
Since MVP makes all the cores the same, that means that Fission Plastic has more color weighting agents in the rim which translates into more gyroscopic stability. Now this comes with a caveat, the lighter these Fission discs are, the less of the weighting agent in the rim. So think of Fission weights as acting like a disc about 10-15g heavier. So a 155g Volt will act more like a 165-170g Volt in the other plastics. What that means for noodle arms is that they can get the same stability of a heavier disc with slightly lighter weights.
Now throw into that mix the Fission discs in the high 160s and low 170s and you have a more exaggerated gyroscopic stability in near max weight discs.
Since there are no Fission Waves, the closest would be a Fission Photon in the lower 150s or higher 140s. Also note that Fission Photons have been coming with a slight dome or higher shoulder so they have more glide than off the shelf Photons in the other plastics. Big arms don't like this disc because they call them flippy. I agree that in headwinds they can be tricky, but if you are use to throwing anny shots with an avertable discs and rolling your wrist, then this may the disc for you. They need hyzer and controlled snap to be boom machines. But they are! I really don't think that MVP needs a Fission Wave. Just get some Fission Photons in various weights, beat some in, get some fresh ones and you will have a single mold that will hold all sorts of lines.
And if you start to really like Fission Photons, the early runs had some board flat ones in the lower 160s that are really stable. You can still find them out there. Not as much glide as the domey ones though.
