Eldar primary, Dark Kin secondary

What sound do Warp Spiders make?

After some soul-searching the last couple of days with the Eldar codex, I've decided to go in another direction.  Instead of using Dark Eldar primary and using Eldar secondary, I've flipped the armies to take advantage of Eldar's stronger grav-tanks.  This is what the current army looks like:

1843
16 kp

HQ:
Farseer (JB, Spear, Mantle) = 160
Succubus (VB, Haywire) = 75*

TROOPS:
3x Jetbikes = 51
3x Jetbikes = 51
10x Warriors (Raider NS/SR, Blaster, SC) = 195*
10x Warriors (Raider NS/SR, Blaster, SC) = 195*

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

FA:
Crimson Hunter Exarch = 180
10x Warp Spiders (Ex/Spin/Fast Shot) = 225

HEAVY:
Fire Prism (Holofields, SS) = 150
Fire Prism (Holofields, SS) = 150
Night Spinner (Holofields, SS) = 140
Ravager (NS) = 115*

Another version at 1750:

1748
16 kp

HQ:
Farseer (JB, Spear, Mantle) = 160
Succubus (VB) = 70

TROOPS:
3x Jetbikes = 51
3x Jetbikes = 51
5x Warriors (Raider NS, Blaster) = 130*
5x Warriors (Raider NS, Blaster) = 130*
10x Dire Avengers (WS, Holofields, TL Scatter) = 265

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

FA:
Crimson Hunter Exarch = 180

HEAVY:
Fire Prism (Holofields, SS) = 150
Fire Prism (Holofields, SS) = 150
Night Spinner (Holofields, SS) = 140
Ravager (NS) = 115*

At first, the looks incredibly skinny, but the amount of weapon options available to me is gigantic.  The Laughing Seer starts the party off strong with reliable and mobile psychic support, alongside a strong shooting force of 3x Eldar Grav-tanks + the Dark Kin's lances.  The Venoms help support the cause as well and the Warp Spiders are fantastic units at killing just about anything.  Drop them behind some and have them stalk other flyer's rear armor all day!  There was a good amount of horde vulnerability with the old list, but I think this list gives me plenty of poison, templates and large blasts to handle most threats thrown my way.

All in all, I think this force gives me a better chance vs. the Tau.  Having Fire Prisms reach out and touch stationary gunlines gives greater reliability at doing damage from range.  Unfortunately, the Eldar race is still too few to present much of a intimidating presence.  Which list do you guys like more?
