I am going to a tournement and have made 2 possible lists for it. Proxies are not allowed and I am not investing more in X-wing right now, so the lists are based on my limited x-wing collection
Expansions and cards: Core, Most Wanted, Starviper, Protectorate, Punishing One (I also have the upgrade cards from Slave I and an extra Mindlink card)

I have worked out two lists with the only difference being Manaroos upgrades

Fenn, ML, title, AT (32)
Guri, ML, AT (33)
Manaroo, ML, Proton torps, Boba Fett, R4 Agro, Guide chips (35)
OR
Manaroo, ML, Boba Fett, R5-P8, Feedback (34)

Which Manaroo build is better or could I make a better list from the things I have?

boba is almost useless without a way to trigger a crit

I know, but he is only 1 point and can break a list like Dangeroo (taking the 12 point title) or Palp lists and still allows me a 1 point initiative bet. What would you replace him for?

drop R4 and boba in favor of K4 security droid
