Now that there are more than two [of the original] Bounty Hunters in the game,
Does any one have any good ideas for a Boba, IG-88, Bossk 150 point builds they'd like to share?

IG88 can be only played with IG88, or it's a waste of points (due to the title),

in a 150 Pts games, you could play a 3 or 4 IG88 list (would bet on 3 for having the canons and auto thruster)

you can replace the feedback array by a bomb (seismic charge), but since the agressor is a big base ship, the ion does nothing to you the first time you use it and you can deal with 1 little damage while all the squadron list (specially the arc dodgers) will do their best not to be in range 1, sacrifiying the +1 attack dice if they don't want to get killed.

Probably the only use of illicit i will ever suggest (untill we get some new one).

Since we doesn't know everything about the wave 7, i won't say annything untill we know more

You're being "tournament anal" and missing the spirit of the photo in the post.

Try some thing fun instead of efficient for a change.
