I have 175g TP Longbowman and a 175g Opto Culverin. Flight-wise I really can't tell a difference. They landed within a 3m circle. They feel different though. The Longbowman has a very flat top, the rim isn't the most common - see the pictures above. I actually do prefer the Longbowman over the Culverin (but I also have no issue with the Blitz or Riot).
Compared to SaintPro, Stag, Northman, Striker both of them are more overstable without an uncomfortable fade at the end. You can turn them over in a headwind, but they never get lost all the way, or at least they put up a fight. You can produce nice flex shots - but you have to give them quite a bit of anhyzer on the release. Released flat you either need headwind or more power than me to make them turn.
Compared to the xXx (I don't have a Felon) they feel a lot less utility disc. Longer, more glide. They should fill the Spot between the SaintPro, Striker... perfectly.
I can''t compare to PD, Thunderbird, FD, I never had one of those.
For reference - they went between 80-100m for me.
