Since you've got a left BP on your first AC, you might as well stick to F73H. It has the best parallel sight, horizontal lockbox FCS. Parallel sighting is how your lockbox will be affected when a gun on the left is equipped.
I guess the others are just your preference (I'd look for a good all-around radarless head and RA btw). Not sure about GAZELLE though. Was never a fan of RJs anyway so I can't really comment on it, other than the terrible cooling stat if I'm right.
