1250 pt list for tournament

So, this Saturday, my local gaming store is holding a 1250-pt 40k tournament. Here's what I plan on bringing:

Haemonculous- liquefier gun- 60
Haemonculous- liquefier gun- 60
9 Wyches- haywire grenades, shardnet, Hekatrix w. agonizer- 148
-Raider- flickerfield- 70
9 Wyches- haywire grenades, shardnet, Hekatrix w. agonizer- 148
-Raider- flickerfield- 70
5 Kabalite Warriors- blaster- 60
-Venom- extra splinter cannon- 65
4 Trueborn- 4 blasters- 108
-Venom- extra splinter cannon- 65
Ravager- flickerfield- 115
Ravager- flickerfield- 115
Razorwing Jetfighter- flickerfield, night shield- 165

Total: Somewhere under the 1250 mark, I can't calculate it right now.

Any thoughts on this list? Constructive criticism welcome.

Personally If I had to field a 1250 Pts army I'd field it pretty much EXACTLY like this. You have a really nice mix of AT and AI units. The only thing I might reconsider changing or dropping is the haywire grenades on the Wyches but that's due to personal preference. I'd spend the points on something like upgrades for your Ravagers / Razorwing like Nightshields just to give them extra protection. Other than that the list looks really solid to me

Overall I like it - if it was me I'd probably make some changes.

The thing that sticks out to me is the Razorwing, which is there to hurt infantry and be light support versus vehicles - I think you could do better.

My alternate thought is this (though double check my math, I may be whiffing it;

Switch the Razorwing to another Ravager.
Drop one Trueblaster so the 4 man becomes a 3 man squad.
Drop the Wych Weapons and 1 Wych from both Wych Squads.
Buy Warriors/Wracks in a Venom. (you could do the Wracks without dropping Wyches, I'm pretty sure the Wych drop would net you Blaster Warriors though.

The difference would be;
-2 Shardnets and 2 Haywire Grenades
-1 Blaster Shot on the Trueborn
+1 Blaster shot and +1 Target option via the new Blaster Warriors
-4 Monoscythe Missiles
+12 S. Cannon Shots
+1 Dark Lance
+1 Scoring unit

Overall you're getting more anti-mech shooting. You're also getting more scoring units, more ability to target multiple enemy targets, and more units that the enemy has to dismantle to feel safe. Also you don't have the dance that is deciding what the Razorwing is doing - remember, if it dies with missiles still on it then you wasted points by not just getting a Ravager. Also, having units that aren't needing to debate between shooting infantry or shooting mech helps make your battlefield decisions easier - and having easier and quicker decisions in a tournament is always a good thing.

@Thor: Those are very good suggestions, and normally I would implement them. Sadly, I am limited by my model collection, having only two Ravages, two Venoms and zero Wracks.
