Its not really a traditonal bracket fire mech, but I see it as a lovely in fighter, in that it can continue to use the GR and PPC even in close quarters. Having two 15 pointers backed by a 20 shot cluster offers a lot of oppertunities, especaly since at 7 hexes the big guns are at short and the LB is at medium -1, making the idea of 'in fighting' somewhat relitive.
Down side is, of course, each weapon does represent a large amount of the mech's firepower eggs, but since it will often remove enemy weapons quickly enough, I'm not too shook up over it.
