I love the viggen, I don't actually have much bound to my stick and throttle. Just the essentials, then some other bits still on the keyboard. Although I like actually using alot of the cockpit switches.
Weapons in the viggen are a little different and confusing at first, but once you try them a couple of times your realize how simple it is.
If your looking for someone to fly with I fly the viggen alot with some friends (were EU based GMT time zone) and I'm always excited to see more viggens in the air.
Edit:
Had a think about what I have mapped,
TV, T0 and T1 are very important as is radar slew.
