Slinky was a fabulous addition to HS. I do still rope drop it, if I'm not rope dropping Rise/Resistance, or last trip got in line at 4 mins to closing. Slinky is super fun at night.
RRR was WAY intense for me when I rode it years ago. actually haven't ridden again since that 1 time. It's a lot. Picking a song tho is SO much fun, and hearing "I Will Survive," while riding that crazy coaster was great! THe kids enjoy RRR, but I'm going to vote for Slinky for this one.
