I'm trying various builds with the K right now and this build is the strongest one for me so far. You can pull off some funny builds with this Mech (like 8SPLAS) but this one gives me the most fighting power. Since the 6MLAS build is inferior the the Jenner's in basically every way (Speed, Heat, Torso Movement) I thought "Why not give it at least some uniqueness" and stuffed a TAG into the CT. You could also (like in a Jenner) go for 5 MLAS and an additional heat sink but I really value the higher alpha strike potential over the heat management. Also this mech has absolutely no critical slots with ferro fibrous. I wish I could upgrade to it, shave a few points of armor and have another ton for a DHS. But it DOESNT EVEN HAVE ROOM FOR THE TAG LASER WITH FF ARMOR Not having the additional internal heatsink slot a 300XL engine would have sucks. Bad.
