I played this build a fair amount, its pretty solid, however I ended up switching out the UAC 5 for an LBX 5 and I like it even better. Hard to jump snipe with the bursting clan AC's, the LBX works a little better in this regard.
Dammit man! Don't you know this is the Nova build thread? At least give us something like "Nova Name".
As all compartments of a clan mech are CASE protected, you're probably better off putting the CT ammo in the side torso. Seems like a solid idea, taking the Nova B and MWO-ifying it.
