Most Impressive Aerial Shows in Vegas?

I did a search for this and nothing really came up, so I'm hoping I'm not being too repetitive! My husband and I will be in Vegas for 4 days in 2 weeks, and want to go see a show or two while we are there. I've never seen a Cirque du Soleil show, but really want to. I've heard Ka is amazing, but H has already seen it. There are so many different shows- which ones are the most impressive in terms of acrobatics and aerial tricks (maybe even some pole)? Any other non-cirque shows that are a must-see? Also, which Vegas strip clubs have the best pole dancers? Thanks! :-)
