I decided to throw my Photon a bit in the field after a round yesterday, and the results were pretty surprising.
I'm really dialing in on these discs. I had a hard time at first with the lighter weights, and struggled to get any distance with them. They were falling well short of my Destroyers. Yesterday, I was throwing the Photons consistently at the top of my Destroyer distance range (a little over 400') and never once fell below my average range (375' - 400') like I do sometimes with the Destroyers. Even when I thought the disc landed short because the shot didn't look like a long one in the air, I found that they were somehow getting out there.
I really like the way they feel in the hand, and find them effortless to throw far. I very rarely put a new disc in the bag, but I'm thinking I might go with the Photons in addition to Destroyers and a King for crazy understable shots and the occasional roller (just learning them). The Photons' light weight mean they are not ideal for a decent amount of shots, so I'm keeping my bottom stamp Destroyer in the bag. If a premium release of the Photon comes out in heavier weights, I'll see if a heavy one can replace the Destroyer. I'm not especially keen on replacing the bottom stamp Destroyer though, because I like what it does, so it will probably remain in the bag.
I didn't think I'd like these discs this much. They have their limits, but they go far with less effort and they can go dead straight if you throw them low or kick into a healthy fade if you air them out for distance.
