switch stuff 7's are easier than regular in my opinion..... you know how a regular 540 is just a 360, spot the landing, 180.... well it's the opposite rotations for switch.... so a switch 7 is just a switch 5, spot the landing, 180 more... stomp. Just do it. And getting them corked isn't bad.
switch corks are easier, but i sometimes do switch rodeos on accident, while going normal i always just do corks when i want, and rodeos when i want. now switch underflips are fun.
