If you want to maximize your shots on your venoms. Get a 3-man Kabalite Trueborn squad and put them on a Venom. Give 2 of the Trueborn Splinter Cannons. The Venom (with an extra Splinter Cannon), should be getting 24 shots with 1 venom. I usually run two together to get 48 shots on one target if I need it. Granted, depending on how fast you go 12 shots on the venom could be snap shots... but you can find situations where you can move and shoot full BS with them.
No mercy for the weak, no pity for the dying, no tears for the slain.
