I saw a few lists this weekend utilizing the R2/SFG combo on Arcs. I’ve also been thinking about giving dedicated a shot. Just not sure dedicates is a good enough gimmick to take up 10 points on this list. But, here’s what I got:

(43) "Matchstick" [BTL-B Y-wing]
(8) Veteran Turret Gunner
(5) Ion Cannon Turret
Points: 56

(46) Squad Seven Veteran [ARC-170 Starfighter]
(3) R2 Astromech
(9) Seventh Fleet Gunner
(1) Dedicated
Points: 59

(46) Squad Seven Veteran [ARC-170 Starfighter]
(3) R2 Astromech
(9) Seventh Fleet Gunner
(1) Dedicated
Points: 59

(25) Gold Squadron Trooper [V-19 Torrent Starfighter]
Points: 25

Total points: 199

If I go with 104ths instead of the Dedicated Arcs, I have room for R4 and Elusive on Matchstick, which really opens up their maneuverability to keep that turret arc forward. Also then have six points to put hull upgrades on the Arcs or upgrade my Torrent (though not really wanting to add much there. It's there to block and add a target lock to matchstick).
