If you run one DBB with 2xBeam Overloads running on CD the javelin is redundant. The javelin is basically a BO it even triggers the BO CD . so it's not worth it . i used the gurambe for three weeks then went to vorcha-r on my ENG . ill try my TAC next but i really am digging the Heg too much to think i will switch for a long time. as it stands right now the guramba is a raptor minus the cloak for a while i liked it i had it all borged up but it was only so so in the end.
