I feel like Karsbi's ability was meant to make them the premier XG-1 Title pilot...Only problem is the best build I could come up with is 37 points...
Lieutenant Karsabi (24)
Wired (1)
Linked Battery (2)
Heavy Laser Cannon (7)
Advanced SLAM (2)
XG-1 Assault Configuration (1)

Slam, focus, stress. Still shoot HLC w/a reroll and focus (for LW Dash players that seems familiar, and is often 4 hits). And wired allows you to reroll (focus) on defense, and/or offense if you spent your focus. Hopefully wired would chip in an evade or two over the course of game, that's probably more than you could statistically ask, but even just 1 is great for a 1 point EPT.
Not sure what to round out the squad with, maybe something like this:
Lieutenant Karsabi (24)
Wired (1)
Linked Battery (2)
Heavy Laser Cannon (7)
Advanced SLAM (2)
XG-1 Assault Configuration (1)
Nu Squadron Pilot (18)
Tractor Beam (1)
Heavy Laser Cannon (7)
Long-Range Scanners (0)
XG-1 Assault Configuration (1)
Darth Vader (29)
Veteran Instincts (1)
Advanced Targeting Computer (1)
Engine Upgrade (4)
TIE/x1 (0)
