Scrap the rails man, put at least on turreted MC with High ammo and corrosive, switch the class 4 Beams for MC OC with autoloader, drop the 7 A cell bank who will cook your ship and instead put a 7B ( more HP - one more charge ) and drop the heatsink and add instead a wanted scanner, so you can double your credits.
Instead of hull and module reinf. packs get some Guardian shield boosters, module and hull protection are useless in a Vette since you will never lose shields lol - and if YOU DO - then you did something badly wrong

....
Your build is way to overloaded, imho, the Vette is so OP you can do all you want with her with half you have massed there...
Anyway, try to get rid of beams, MCs are the top killing tools.
Your build will work, for sure, but again, is an overkill.
This is my all round build - you can fight at will 2 wings of Elite Pirates at once, included 2-3 Annies, with no big sweat AND still making a decent freighter - if need arrive.
