I love the lowly gold Squadron Y-wing with a TLT. But as we all know if someone get's close on your tail you could be dead pretty quick. So what's the answer. Well one answer is bombs.
Imagine three TLT Y-wings each with a seismic charge. Then you put Sabin on a HWK and keep her away from the fight. 2 auto damage to someone who get's on your tail sounds pretty good.
