I am looking at putting a list together with Bossk and Ketsu Onyo, and was wondering if Gyroscopic Targeting or Engine Upgrade would be better on Ketsu (or something different entirely).

To be honest, I don't really get the point of Gyroscopic Targeting, moving the mobile arc at the end of the turn doesn't seem that useful to me. Is it just to try and anticipate where ships will be next round, and therefore get a free action before the round starts?

I should say that this list is for casual play, not competitive. I haven't been able to play X-Wing for a few months now, and have managed to get a weekend away to play X-wing 24/7 and drink real ale (sounds like heaven). I will be trying to use as many of my ships as possible over the weekend, so I will probably only use this list once, which is why I want to get it right beforehand.

Any advice from you guys would be appreciated!

Engine is best for Ketsu, she doesn't want to move her arc around much, and REALLY wants range 1. Gyros are better for Assaj, who doesn't care.

Gyros are great generally though. You can use them to fake out your opponent at the cost of an action to yourself, or often you can use them and your opponent can't do anything about it anyway.

Engine on VI Ketsu is good

Shadowcaster with Engine is pretty much the faster ship in the game, and a bit of post move repositioning is always good.

I've never bothered with Gyros flying my Shadowcaster, and never found myself wishing I'd taken them either.

I will go for the Engine Upgrade then, thanks guys!

Over the past year I've flown against quite a few Lancers. Most of the time, I've been using Stressmule Braylen and he totally wrecks Lancers without Gyros if I can catch them with the mobile arc pointing sideways or forwards. It means that my ships can pursue the Lancer in complete safety and kill it before it loses all the stress.

On the other hand, if you are unlikely to face multiple-stress-token-dealers, Engine Upgrade is much better.

While I've gotten a lot of good use out of the Gyro and stick it on the majority of my Lancer builds, I'll agree with the majority and say that EU is better for Ketsu.
