Advice on Current Meta-Game - Large ships plus small slippery ships?

By junkygood, in X-Wing Squad Lists

So, it seems that all the lists run in "casual" games being played at my local gaming store have a common theme: Large ship plus small highly maneuverable ship(s).

Example of what I've played against many many times:

Decimator (almost any build, Ramming Oicunn, expose Chiraneau, etc.)

with Whisper or Echo

or

Firespray (Kath mostly) with PTL Soontir and PTL Turr.

and then the standard fat Han or chewie & lando.

I need advice on how to counter these lists that i assume I will see in an upcoming store tourney. The time limit is 60 min. so points are my priority. I'd rather run a unique list to counter the above builds, and not submit to the "can't beat 'em join 'em" attitude.

I've tried to min-max for ion tokens to hopefully run the big guys off the board but the current ion mechanics feel nerfy. Any suggestions?

I did win against a fat chewie and Lando with:

Oicunn + Predator + Reb Captive + Gunner + Ysanne + Engine Upgrade

Doomshuttle

Gundark

Can that list compete in the current meta-game?
