1850-2000 point list

I'm fairly new to 40k and I haven't played too many games. I've been playing at 1300 points because at this point that is all I have, but I plan on making a large order soon and I want to get some advice on a list before I do.

HQ-
Haemonculus, Liquifier, Venom Blade
Haemonculus, Liquifier, Venom Blade
Haemonculus, Liquifier, Venom Blade
(Each in a squad of wyches)

Troops-
-9 wyches, hydra gauntlet, Hecatrix w/ agonizer, all w/ haywire grenades (in raider)
-9 wyches, hydra gauntlet, Hecatrix w/ agonizer, all w/ haywire grenades (in raider)
-9 wyches, hydra gauntlet, Hecatrix w/ agonizer, all w/ haywire grenades (in raider)
-10 wracks, 2 liquifiers, Acothyst w/ Venom Blade (in raider)

(Should I drop the gauntlets and give an agonizer to the Acothyst if I keep the wracks?)

Elites-
-4 Trueborn, x4 blasters (Venom)
-4 Trueborn, x4 blasters (Venom)
-4 Trueborn, x4 blasters (Venom)

Transports-
Raider, Flickerfield
Raider, Flickerfield

Venom, Extra Splinter Cannon

Heavy Support-

Ravager, Flickerfield, Night Shield
Void Raven Bomber, 2 Shatterfield missles, Flickerfield

I'm currently running something similar, except with scourges and without the extra unit of wyches, the unit of wracks, the third blasterborn squad, or the flyer. So everything that I haven't bought yet I'm willing to change. (only have so much money).

The main thing I'm iffy about is the wrack unit, as I've never seen wracks in action, but I hear that they are a great choice. T4 is nice but I'm used to initiative 6 with wyches. xD. I've also considered a unit of incubi w/ an archon in a venom which would require me to drop the wracks and replace them with a unit of warriors w/ a blaster in a venom due to the cost sink. I'm torn at the moment, so any advice would be helpful, even suggesting something I haven't thought of yet.

If I were to run this list at 1850 I would probably drop the hydra gauntlets, a wych from each squad, and a trueborn from each blasterborn squad.

The main reason why I prefer flickerfield on the assault vehicles is because i play against a lot of Tau and Chaos. Between the Helldrake S6 flamer and Tau ignoring cover too often for my liking it saves my vehicles more often than Night Shields would. I have a knack for making my vehicle saves too which helps (: I also think it helps whenever I go second, as theres no jink if you cant move.

I like your list and your reasoning so Im inclined to say stick with it.
Im a huge fan of incubi but in your list where you're compelled to take multiple haemies I feel you'd be over spending on HQs unless you just went with 4-5 in venom without PGL archon and used them for countercharge duty. Then its pretty much a straight swap for the trueborn which actually sounds more apppealing and incubi are good against CSM.

For other suggestions, I feel you would benefit more from splitting one unit of wyches into 2x5 in venoms instead of the 3rd full unit giving you 3 raiders 5 venoms. You can find the missing pts by losing those hydra gauntlets.

Thank you for the advice. If i was to go with the incubi and archon that is definitely how I was planning on doing it. It's a tough decision and I know I want to eventually try both whenever I get enough money.

I had never thought about putting some of the wyches in venoms but now that you've made me think about it it wouldn't be bad. 24 more poison shots and more targets for the enemy to have to shoot at. I would have to drop the haemi in the unit as well, so I would have to think about it,(I'm obsessed with haemi's for some reason) but it would be worth it. Depends on how much money I am willing to spend next month, but I will certainly try this in the future if I can.
