I LOVE GRONA LUND!!!! been there twice and for the small space the park has, the use of it is fantaataa! jetline is one awesome ride - if you sit in the back row, on the "OMG" drop u get some airtime n then that "100G" moment at the bottom! Infact you get loads of Gs at the bottom of the first drop, when sitting by myself, the restraint next to me was pulled all the way down by itself! Jetline really does run through those brakes, the only ones that seem to slow it down are the ones at the very end.
as for vilda musen - its another awesome ride. it is weird though, you get the great sensation and drops of a normal wild mouse then at the end you have a turning drop into and extremely tight, highly banked upwards helix. the helix is right above the pavement below and gives a good views for on lookers.
That fun house is massive and the best one ive ever been in - LOVE IT LOVE IT LOVE IT!
