Purely second-hand but I recall reading a report from a Jaguar pilot on exchange with them. On an orientation flight in a Viggen he was flown down a snow covered logging trail in AB below tree top height - said he had never experienced anything quite like it. When he took a different Swedish pilot up in his 2 seat Jag he established at 200' AGL, engaged min AB and passed control to the Swede who promptly pushed the nose down and repeated the same performance in the Jag.
The RAF pilot stated that the Swedes were some of the most capable FJ pilots he had ever seen.
That was from Air International I believe from many many years ago, but it has always stuck in my mind.
