Here are some ideas to start off, from JBLP1 and my own sets. I'll definitely add more later. These are just levels I'm decently familiar with. I'm not taking into account any possible difficulty restrictions the set may have (though I don't think it should have any), so these are levels I find interesting and unique, with no regard to fulfilling any sort of requirement for easy levels.
tl;dr here are some levels I like.
