A tractor beam on a PS1 ship is almost useless. If you want to keep it, swap it around so that it's on Ryad, that way your entire squad gets the benefit of the tractor beamed ship having -1 agility.
With 2 Deltas, there are 3 shots that come after the Tractor Beam fires (the primary shot on the TB ship and the Ion+Primary on the other Delta). I'm not a huge fan of the Tractor Beams, but without points for the Ion Cannon in the squad, it's not a bad choice. If I was going to make an ace a TIE/D I wouldn't skimp on points, and I'd just give her an Ion Cannon.
