Greg accidently picked Healing Vision angelic mix, which is a 9 foot I haven't even tried before (the 7 used to quickly consume my endurance, so I've been avoiding it until I get a few more 9s under my belt) and so I was forced to try a 9 foot in the arcade. I surpised myself by getting 3/4 of the way through before just running out of steam. I could definately do it (on first stage) if I had the endurance for it. This is another data point that my problem with the arcade is I just don't know the songs.
After that, I was wheezing, so we did cowgirl on maniac to cool me down. It felt good to be able to do an 8 foot as a cool down song.
Next time I think I will try a 9 foot that I've passed before and feel like I have a good chance of passing again (like afronova) and prove that I can do catas in the arcade.
