I alternate between this build and the XL300 variant. I've found that in PUGs I prefer the faster speed to avoid being abandoned by my weird teamates but in semi-organized group drops I can hang out with some other slower mechs and lay down the same punishment while being able to soak up damage and sacrifice one of my UAC5's and dramaticly increase survivability. Sort of like Yen-Lo-Wang XL vs STD.
