It sounds like you'll absolutely love Candymonium.... SkyRush is tied with i305 as the most intense coaster(s) that I've ever been on but it's so glorious. Where i305 has a ton of positive G forces, SkyRush has insane negative G forces.
I've not been on Expedition Everest as I haven't been to Disney since I worked there in 1999 but if you love that coaster you'd probably absolutely love Hagrid's Magical Creatures at Universal Orlando.
