I've been experimenting with my 'normal' MRM120 build on this clunky mech, trying to balance it between MRM's and SRM's. One JJ for added mobility. Heat's manageable; moreso than MRM120. This might be a bit low on ammo until skilled, but seems good on paper and in the training grounds: _ Oh ... note. Since the MRM40 triggers ghost heat for adding more to it, I put the SRM's in one weapon group, then the two MRM's in another on chainfire. That way I can stagger them by 1/2 a second.
