Hiya,
I'm in exactly the same situation, looking for a successor for my Crossfire.
I had the chance to demo a Neos 99 for a week but stopped early. Of 7 jumps, 2 openings were ok, the other 5 were incredibly hard. On the last jump, I heard my neck crack and couldn't move my head without pain for the following 2 days. But I have also heard of people with softer openings, so I guess it all depends. From my point of view, I can certainly not recommend the Neos.
Actually a pity because I'm an Icarus fan and liked the flights a lot. From the few jumps I did, I'd say a mix between a Katana and a Velo.
I haven't jumped a JFX yet. I'm looking for a demo but it seems like they will be very rare in Europe for a while. Daedalus will post the dates and locations on their website.
