The Hunchback, Trenchbucket, and Thud are all ground-bound, and the 'Bucket is not as tough as the others. By all means field a stock Quickdraw, but there's a canon variant, the QKD-5A, which replaces the LRM-10 & ammo with two more medium lasers and more heat sinks. This makes it a nastier knife fighter, with bounce.
(It's also a very easy mod to the mini - cover the LRM slots with clay, even paper, then glue a little pip on each flat surface for the MLs. I can't help it, I don't play WYSIWIG, I just like modding minis :D )
So think of a Y formation. The Thud and Hunchie are forward, the Treb is in the rear supporting, and the Quickdraw floats in the middle and deters backstabbers. My third M-bill, if you like :wheelchair:
