Unless I'm mistaken, Isobel McGregor is also a Spec Ops model, so she would take the place of the spec ops choice that you've made. As for hacking in Ariadna, too, there's not a lot of need for it - the only thing it would let you do is hack incoming guided missiles, and while that's a good thing to be able to do, it isn't often that you face those.
Other than that, all I can comment on is that Tank Hunters are the duck's nuts, and Uxia is a total beast - she's one of the very few models that have superior infiltration, and that is such a strong rule that I cannot suggest you make full use of enough
I've decided, in the interest of being able to play with a fully painted army, that I'll be taking my Yu Jing to Paradiso Firefights 2. Unlike the last time, though, I'll be taking vanilla, rather than the Japanese Sectorial.
First list:
Yu Jing | 10 models

A fairly straightforward list that packs in 3 HMGs and a Spitfire. I can do smoke tricks with the Hsien, the Hac Tao has the TO Camo for surpise attacks, the Karakuri spearheads the assault, not caring about most ammo types while having a decent chance of success against most targets with the Mk12. I'd really like a higher ROF weapon on them, because their BS is only 12, but as the hard working model in the list that should be clearing out the enemy's lighter foes, the Mk12 gives me some ranged options that out-threat standard rifles and combi-rifles. Depending on how it plays though, I might swap that out for the combi-rifle version, which lets me upgrade the standard Keisotsu to a Paramedic Keisotsu.

This list is the one that wants to tackle enemies that are running TAGs or a couple of key heavy infantry pieces. While it seems fairly similar to the first list, the Daofei has infiltration and normal camo, letting him play more agressively, but without such a distinct advantage in a stand-up firefight. Along with the Guilang, they're to clear a path for the Oniwaban to cut open TAGs or serious Heavy Infantry that a surprise burst of HMG can't deal with. Because the Hsien is probably going to have to play a more critical role in this list as my primary beatstick that sits around my back lines, I figured that having the doctor upgrade on my Spec Ops was more useful than the extra BS. Being able to keep him alive for longer, and especially being able to repair a single lost wound on him, should help the list stick around a bit longer if my infiltrators fail to do their thing.
So, what do you guys think? Would you feel comfortable facing a list like this/ know the tools that you'd need to tackle it? They're both similar to the lists I ran both last night and Monday night, and it seems to be a list design that's working for me at the moment, so I'm pretty confident with how they should both play.
