New tie defender build please help

By Bents1986, in X-Wing Squad Lists

Hi all im new to this, im going to a small tournament and was thinking of taking this list:

Countess Ryad (36) - TIE Defender

Push The Limit (3), TIE/x7 (-2), Twin Ion Engine Mk. II (1)

Colonel Vessery (40) - TIE Defender

Ruthlessness (3), TIE/D (0), Twin Ion Engine Mk. II (1), Tractor Beam (1)

Lieutenant Colzet (24) - TIE Advanced

TIE/x1 (0), Advanced Targeting Computer (5)

I have been thinking of swapping ruthlessness with outmaneuver but i was thinking that i could move them with tractor beam plus - 1 agility then ruthlessness can be used twice per turn or get the ship in place for a second hit.

A defender with green k turns and free evades plus push the limit is awesome.

Also like the idea of mixing my tie advanced to use target lock for plus 1 hit then use it at the end to flip damge cards.

Any help would be great!

Thanks
