Wouldn't really recommended them on the vulture, sure it can work and its a personal opinion.
Something like this
http://coriolis.io/outfit/vulture/04A5A ... BhrMEZLDiA could work, but power demands get pretty tight. So tight in fact that you just turning on the KW scanner will have to switch off one of the beam lasers.
It is a little light on shields so I would be cautious attacking wings with this setup, but if solo, the police ships can help.
All this talk of large beams had me curious again so I went hunting for some to try on the python.
Took a bit of hunting but found some (in sol again, on Abraham Lincoln I think)
Also needed to bump my PP from c to B, currently testing with a cannon in the third, but contemplating getting another beam there as well. But that might even need an A grade PP to work...
Beams are fun and they do noticeably more damage at range where pulse pretty much feel like water pistols outside a Km.
