Pretty straight forward. Harass with LMGS and Target weak spots with SNPPC. Optimal ranges sync pretty well well, it can be a bit hot but its actually pretty manageable especially with the right skill nodes.
I'd ditch the MG's, rebalance the armor, give it its max engine, and add some JJ's. Pity we can't add MORE JJ's. The SNPPC's might work better on a different UM chassis, so you may as well take advantage of the SC's unique increased speed: Like here's Baradul doing dual SNPPC's on an UM-R63, where the weapons are in the ST instead of the arm, which is so much better. However, that one only has an XL180. The Street Cleaner is faster.
5/5, This mech is allot of fun, the range quirk helps the SNN-PPC, and the right side is a little smaller so the lower armour is not so bad. Runs a little hot so get Operations, and some extra range nodes, and you are in business!
