Here is my (probably shoddy) Tyranid list at 1500 points
Mostly I am excited about using the swarmlord with a 2d6 assault range, maybe he will get into h2h occasionally =) Also, I haven't looked at all the powers, but first try might be everyone using Biomancy.
Biomancy has Endurance to give a unit FNP which is the power I want. However, its primaris power is smite which is AP2 so its not bad. Iron arm and warpspeed are good for any of my psykers. Enfeeble is a great debuff. Life leech can heal my characters (all have 3 or more wounds) as well as being S6 AP2. haemorrhage I am not to keen on but no armor or cover saves are not bad.
telepathy also has some interesting options. Psychic shriek can do a ton of damage. dominate can slow units down. Mental fortitude is worthless to me though. Puppet master is pretty neat, i think i would only want it on the tervigon though. Invisibility is cool but only the swarmlord can cast it since its warp charge 2. I would love an invisible swarmlord but i think iron arm might be more useful. Terrify is i think the best (warpcharge 1) power out of telepathy as it takes away fearless (although i guess it does not take away 'and they shall know no fear"...I wish the tervigon was mastery level 2 =(
