I normally wouldn't recommend such a heavy/hot build on such a small 'Mech. You might try to fit a couple extra DHS. In the end, the Katana Kat is a difficult 'Mech to build. It has a small engine capacity, so it runs slow for a 'Mech with so little armor. It does have the option for alot of JJs, so poptarting is probably the best way to go. But in that case I'd suggest weapons with more range than Snub-PPCs.
