You've heard of the 1-2 punch? Well this starts with 4 ER MLs and then finishes with 6 SPLs, so it's a 4-6 punch. The 4-6 defense in Gridiron Football is called a Bear defense. So...Bear Punch. Anyway, the Bear Punch isn't designed to be used as an alpha. You use the ER MLs for midrange and the SPLs for short range. It runs really hot (if you alpha, you die) but if you have good trigger discipline it can be very powerful. I've tried all-SPL builds and found they lack range, and all-ML builds and they lack heat efficiency. This is a good compromise.
