Just a quick follow-up: I did get my Twist Saturday, and everyone is right, they're the goods.
Twist/Spinners are a great way to try VV, I did it somewhat backwards though. Went from a 650 mah passthrough to the VAMO, then added two sigelei v8's, (got a great deal on them), and sigelei ZMax. Then I went with the 1300 mah spinner. Usually take the Spinner and or one the V8's with me when I am out and about.
Congrats on your new Twist, and welcome to the world of VV.
