I'd probably switch one of the bolters for a shotgun.
Those are pretty cool, pretty good and I like to avoid too much doubling up on a single gun.
Guaranteed pin is a joy if there's a Butcher bor berserker coming for you
I'd always pick tactical flexibility over raw killing power. Smoke grenade saved the hide of one of my cops many times, blocking off firing lanes or forcing the enemy to relocate, and nothing is sweeter than blinding a group of enemy gangers, turning a fierce firefight into a shooting gallery.
