1000pt with Pain Engine

Fellow Archons,

I've just finished reading some older posts on the Talos Pain Engine, and I'm very excited to try one out. I've managed to cram one into the following list (see below).

I have two Kabalite Gunboats that I have had success with, although I had to drop Night Shields. I normally run 7 Wyches with the Succubus but now I've put them in a Venom and they'll mostly be used for tank hunting and if they live through that, they can try and grab a late objective.

There are two main threats in the list. The idea is for the Incubi/Succubus to move forwards and assault (if there is an appropriate target) while the Pain Engine stays closer to home moving up slowly with its Splinter Cannon. It can protect my objective and make my opponent hesitant to deep strike into my shooting line.

What are your thoughts on this list? Am I putting too many points into Heavy Support? Troops too weak?

List:
-----
Succubus w/Agoniser - 85

10x Kabalite Warriors w/ Splinter Cannon in/ Raider w/Splinter Racks - 170
9x Kabalite Warriors in/ Raider w/Splinter Racks - 151
5x Wyches w/ Haywire Grenades in/ Raider w/ Splinter Cannon - 125

4x Incubi in/ Venom w/ Splinter Cannon - 153

2x Ravager - 210
1x Talos Pain Engine - 100

I would highly recommend giving the talos the twinlinked liqufier, it's a fantastic weapon and only 5pts.
