Just like the Jenner-D, use this to brawl. You have to protect your right arm, but the amount of JJ should make this easier.
more cooling!! I'd rather be able to fight more vs support more with less JJ and BAP. Good call on not being tricked by the dumb PPC quirk when the 10k is naturally the 2erppc jump light. Edit: Also, you think you'll get in 50 volleys of srm?! At least lose 1t for another DHS or something...
loosing speed is a no go for me, sorry. Going to stick with the XL250. Also going to stick with 4x JJ, as that is what makes this mech unique compared to the Jenner. If I needed a cooler loadout, I would run a compromise of yours and my op.
I actually made this loadout already, it's here- Uptonner A1 https://www.mechspecs.com/threads/pnt-9r-up-tonner-a1-1x-srm6-4x-mplas-4x-jj-xl250.8710/
