As the title says thank you to everyone who gave advice and calming words.
As I said I would, this is the list I took in the end:
Poe + R2-D2 + Autothrusters + VI
Miranda + TLT
Tarn + R7 + IA
As you may have noticed I chickened out and changed to a staple of mine (Tarn).
Before first game:
K-Wing broke, had to borrow a friends. (Thanks again if you see this)
Game 1: Loss
He took Han + Miranda
Tarn took a beating ( That's what he's there for, distraction FTW)
Poe almost unhurt untill.... i broke my golden rule, I 1.didn't double check my dial 2.didn't turn my dial to match facing. I flew him straight off the board.... FULL HEALTH POE!
I'm angry at myself for that.
Game 2: Bye
Game 3: Loss
He took Wedge Wes and keyan.
Started well. Wes went down like he was made of paper but then Wedge (outmanoeuvre + BB8) lined up. Poe folded. No dice, took a crit. He died next turn.
Long story short Miranda removed Wedge and did a fair chunk to Keyan but ultimately she went down to fire power
Game 4: Win
He took Lats (the yv666 ps 5) and Boba.
Nothing fancy to report tbh. My opponents dice went cold after taking Tarn down to a hull. After that he couldn't really do anything.
TL;DR 1w/1b/2l
Good fun had by all. Finished 10th. Came away angry with myself for the Poe cock up but I have a C3PO alt art and some new people met (I'm a bit of an introvert so this is big for me).
So thank you again for the advice. May the force be with all of you and may your dice forever run hot.
