I don't actually have one of these myself but I figured it would probably make a good replacement of my BJ-3 though it isn't quirked as good. I have not actually played any of the Uziels so I don't know if the quirks on the 2S make it better than this 6P but from what I see I would prefer the even higher mounts(and convergence) of the side torsos over the arms despite their pretty nice height and lower arm actuation. I would assume a lot of other versions would get a targeting computer for more velocity or downgrading the engine for more heatsinks. However, on paper(not counting quirks) this seems much better than my 2xERPPC BJ-3 in many categories if you look past the min range.
Interesting take. I think Uziels are generally considered too squishy, so a poptart idea should work well for them. I think a BJ3 with backup weapons within the min range (lights will get close eventually) and ppc quirks will out perform generally though, especially since you can use the vertical mobility of the arm mounted PPCs and Heavy PPCs are extremely hot!!
