Technomancers, Just which complex forms do they need Options

[Xeros]

What complex forms would be vital for a techno to have. I am trying to make my first SR4 character, and the cost of complex forms adds up fast. There is threading of course, but that must be sustained. There is also sprites, a valuable and useful tool for many purposes....but a techno has to have some things ready and on the go.

I am thinking things you would use very commonly, and over and over (analyze, scan, exploit, stealth, maybe spoof), things you need to have instant access to, that you wouldn't want to spend a turn getting ready for (armour, maybe attack), maybe things that sprites can't do (no sprite has ECCM, and considering it can shut you down cold...), what complex forms would you *definitely* put on a starting techno.

Things like defuse, data bomb, edit, even encrypt...you will only do on rare occasions. Many programs can be ably satisfied with a helpful sprite, and even a force 4 sprite will probably be managed with no fading by many able technos. Browse is useful, but you are rarely under pressure while you do it. Same with decrypt. Sniffer and track would be handy...but I am not sure they are mandatory for starting rollout.

I am also not clear what the command program really does. When you do you bother actually rolling it? Once a drone is subscribed to you....well, they accept commands. I haven't found where you need to actually roll that.
