I was "brought up" with roundabouts. I only indicate just before my exit... just to let people at that same entrance know that they now have a gap to accelerate onto the roundabout.
On a multi-lane conventional roundabout i would tend to stay in the outside lane. If the roundabout is empty of traffic and I am going straight across I'd usually take the shortest path through tho', using all the road.
I am not sure I'd dare to do that in Canada as the populace is just not used to roundabouts. In the UK, France and Spain it works well and one can get through them quite fast with some care and anticipation as one approaches the entry point.
They are just second nature to me, but I remember thinking as a learner, how can you use mirrors, indicators, clutch, accelerator, steering wheel, and look where you're going all at the same time! I think 3 lane roundabouts are scary as a learner, because you don't have much space to make your decision and move.
Now my commute involves 3 x 3 lane roundabouts, it's easy, left lane for turning left, middle lane for straight ahead, right lane for turning right, and filter across lanes toward the edge as you go round.
