I finally bought Thunderbolts, and of course, I chose the 9S and 5SS as my first two. But then I had to pick a third, and this is the one I chose. And here is the build I use on it: Decent brawler, with a nice high alpha w/o heat penalty, nice range on the LPLs, enough DHS to make it worth it, and a pair of JJs for when you need them (Canyon and other similar maps). It's been working well for me. Here's a match from today in it (still not mastered).
I'm pretty much building my CW Dropdeck around LPLs. BJ-1X and TDR-9SE. Both have great quirks for LPLs, good agility and this even has JJs. I'm looking at dropping the SRMs and running STD engine. The LPLs are really my focus!
