4/5, I love HPPCs, didn't know the PPC blackjack with them hadn't been posted yet! Might be a bit too hot/large for the blackjack to support it with enough DHS honestly.
I thinks it’s quirks for dissipation and heat generation should make it just toasty, plus the extra velocity is great.
With recent DHS buff, this build should be revisited. XL220 with 4xJJ jump jets, but the same amount of DHS XL225, +1 DHS, 3xJJ, lot of armor compromises
Xl seems a little too unforgiving, especially because a of little to no arm armor, and if you lose a side in LE you’ll still have 7 heat sinks and a HPPC, even though it’s slower Also, more than 2 jj seem unecessary
