Hi,
Have a game set up for Wens against my main opponent using Beil-Tan Eldar (very Aspect heavy, light on SH/Titans.) I have generally been getting the hang of Steel Legion, but tried SMs for the first time a couple of weeks ago and got my as(s)tartes handed to me on a plate...

Hoped someone could show me where i was going wrong.
Think i tried to do everything last time - bit of air, bit of termies, but of armour...lot of nothing.
This time i thought i'd try going hard in the air with 2 thunder bricks with a small but solid delaying force (tacs/wirlwinds) holding ground and setting up for the air assaults. The scouts/Speeders/preds designed to look lively and making sure the tacs don't get flanked.
