This is very good news indeed - but sadly to far out for a tourist comming from overseas. Maybe someday on a TPR Tour...
My uneducated guess on re-making a broken-down shuttle-loop would be to remove the whole original trains and launch assembly may it be drop or flywheel and only keep the original track. Then put a new train onto it and equip it with a LSM/LIM launch system. I think Gerstelauer could do this but as said with a price.
No way. While LIM/LSM launches are fun, they just don't compare to the kick-start of GL's flywheel launch. Even though the acceleration was slower than the LIM/LSM coasters, it FELT faster. Really. GL was by far the best of the Schwarzkopf shuttles in the US (I'd vote Turbine just slightly higher because of the indoor/outdoor setting) and unlike other versions, they didn't slow down the train at all on the reverse trip. The back spike was the best part of the ride!
I've not been to Cliff's (that 800+ mile drive is a killer) but this will make it an absolute must-do park for me. This can't happen soon enough!
