Great to hear some love for Rich Ground and Banshee!! I have both - that whole collection along with Warm & Cozy is wonderful.
I also loathe chunky glitter (didn't like it even when I was 13, heh heh) but for some reason Banshee attracts me.
Banshee is really pretty! I remember when i became addicted to MAC years ago, Banshee was alreadyc onsidered LE so i got on on eBay after loving it so badly. But when i tried it, it just wasn't the same in the pic & i only used it a few times. The colour payoff was awfula nd it was kinda chalky. But last week i was at a MAC counter and took a swipe at it (oh memories of my Banshee) and it was actually very nice. They obviously re-formulated it and its more shimmery and smooth instead of chunky glitter!
edit: now after reading more raves on Banshee, i think i need the new one now!
