I'm not really in the market now, but I thought you guys might find Phlster's new offering interesting:

It seems to check a lot of boxes: integrated body contour, ambi, compatible with a couple different wing setups, compatible with the popular attachment methods (to include DCC Clips or the new-ish DCC monoblock).
NOTE: I'm in no way affiliated with Phlster or any of their vendors... just thought it was neat.
