For work i would go with IG + IS and see what happens. If you need something stronger, A314 will do the trick. IG is told to be A314 smaller brother, as it gives a less serious vibe, although the respect is definitelly there.
For breaking the ice and starting conversations with new people, IO.
For making girls interested, AMMO is your best choice. You can pair it with IS too.
I think IS goes good with everything, so you can´t go wrong with that.
Anyway, that´s just my opinion. You may want to read around and ask some questions.
If you have not already done it, there are some threads you should not miss:
Most of them are in the man´s stiky section. Start there, and after a while, you will know everything you need to get started.
Alos, lear how to use the search function. It will be very helpful when you want to start researching about certain products.
