Highest "viable" build you could manage. I do like the cut of you jib, so I'd say it has a 5 star potential.
The xl255 is a 5* for me, used it in the whole Victor tournie and got it done with no problems. I put the LPL in the arm tho, the JJ in the same side of the ECM and 1 point less in the head armor and 1 point in the left arm, small mods anyway.
I'm running a slower version right now (I didn't have an XL 225 or 235). I call it the "Five Pound Bag"
