I've ridden it several times, and it's pretty cool. The best part of Jetline is a steep twisting drop to the right (Like on Thriller/Texas Tornado first drop) where you actually gets some airtime and it has a couple of tight helices. It runs very smoothly (built 1988) Overall a pretty good coaster but i like the longer Swhartzkopf at Liseberg better. For 2003 a wildmouse will be built over and under Jetline which will make it pretty twisted.
Cool that you like the Swedish coasters...
