Hi Q,
I'm on my second car with paddles. They seem unintuitive at first, incredibly so, but when you practice a bit, it's fine.
One word of caution though - don't start off using them in S mode! Practice first in D, overriding the normal automatic selection, probably by choosing a higher gear when cruising or a lower one to slow down without braking.
If you go for full override (in S mode) it can get a little hairy until you practice (my brother-in law pulled a downshift when he though he was turning off main beam in mine!!!).
At the end of the day, I think they're there just for an occasional bit of fun; most of the time the gearbox gets it right; although it does hang on to lower gears a little more than necessary.
Have fun and enjoy either way!
Cheers,
Jon
