DEcisions, decisions

First, my army list at 2K.

1998
20 kp

HQ:
Asdrubael Vect = 240

TROOP:
5x Warriors (Raider NS, Blaster) = 130
5x Warriors (Raider NS, Blaster) = 130
9x Wyches (Raider NS/FF, Hekatrix/Agnoizer/BP) = 215
10x Wyches (Raider NS/AS, Hekatrix/Agnoizer/BP) = 220
10x Wyches (Raider NS/AS, Hekatrix/Agnoizer/BP) = 220

ELITE:
3x Trueborn (Venom NS/SC, 3x Blaster) = 156
3x Trueborn (Venom NS/SC, 3x Blaster) = 156
3x Trueborn (Venom NS/SC, 3x Blaster) = 156

HEAVY:
Ravager (NS/FF) = 125
Ravager (NS/FF) = 125
Ravager (NS/FF) = 125

This list is really effective in all-comers list vs. all scenario based missions except for kill points.

However, I want that to change.  Even though the Warrior Raiders put down a lance shot from the back while providing a solid scoring option, I feel like there might be better options.  Here are some of them.

9x Reaver Jetbikes (Champion, 3x Heat Lances) = 244
10x Scourges (Solarite, 4x Splinter Cannons) = 260
2x 5x Warriors (Venom NS/CC, Blaster) = 135x2 = 270

The Reaver Jetbikes offer solid damage vs. any infantry unit they pass over as well as armor-threatening Heat Lances once they get to the back field.  Scourges, as fragile as they are being Jump Infantry who's often times exposed, provide a ridiculous amount of firepower from far away.  At full strength, they can jump 12" and shoot 18" with their Carbines/Splinter Cannons.  This adds up to 30 Splinter shots with a 30" threat on the move.  They can also stay in the back and offer a solid shooting solution with 24 shots from 36".  Next, we have the 2x Warriors in Venoms that sit in the back, score and shoot.  They're relatively safe because of the low profile of the Venom, the Night Shield and Flicker Fields.  The difference between these three units is that one shoots really well, one contests really well and one scores really well.

Which unit do you think fits better in the list?  I'm all ears.
