I've been trying out the nozzlenoses recently and I'd suggest those as well; they're tremendously precise, have almost dual squelcher/pro/.96 range, and if you can keep a cool head in the middle of a fight, proper timing will net you near-aerospray fire rate with a 4 hit kill. I've also had a thing for disruptors, but if you snag a bit of damage up you can make fantastic use of the burst bombs the L-3 D comes with.
With both you'll want to crank up the run speed, as the mobility on these things is fantastic. Also ink resistance is almost essential for this weapon, at least for me. Both can also make good use of bomb range up if you want to commit a main slot to that.
On the D you'll want some swim speed for the Kraken and some damage up to augment the burst bombs and net you a direct hit + single pellet splat. (I think you need 3 subs or one main for this). Boost that to 6 subs/2 main/1 main + 3 subs and you can land 99.9 damage with three pellets, which is enough to splat in one trigger pull if they've been in your ink at all. L-3 D is also more Ink hungry, so ink recovery might help more than you'd think.
For the record, I've heard that this weapon is most efficient when trigger pulls are at 180 BPM, though I've not tested this myself.
