Venom + crew

At the moment I am new and I have a few questions about Venom + crew

Venom is smal quick troop carrier and it can shoot pretty oki.

You can put 3 kabalite trueborn on a venom + an extra splinter cannon + NS
Give the 3 trueborn some anti tank nades (haywire nades?) and you can kill tanks or just shoot other troops for a nice price of points.
This any good? or I missing a point?

I'm not sure, if you missed it, but there are actually two downsides to this.
1. You can only use one grenade in the shooting phase, so it is neither reliable, nor powerful.
2. The grenades only have a range of 8", which is rather short to reliably take out tanks.

I guess it works as a backup plan, if you want to play anti-infantry Trueborn, but want to have an option to hurt tanks at all.

I'd get the 2 Splinter Cannons for those Trueborn. With Night Shields, it's 131 points for 4 cannons (up to 24 shots). I wouldn't get haywires, 3 is just not enough, and you should be shooting from a safe distance at all times, soo...

HW grenades are there in case you want a close quarters unit, which is not the case.

P.D. And if by any reason you take Sliscus in your lists, this is a good place for him at the beginning of battle and at turn 1 let him join a combat unit.

4 Splinter Cannons for 131 points sounds realy nice.
3 Hawwire nades is not much but for 6 points seems a nice price.
offcourse the 4 Splinter cannons are for long range shooting...but if the enemy drop some troops with armour value near your venoms...a Dreadnought or a landspeeder for example.
then 3 haywire nades can be handy?
