RC - For drillings we are thinking shorter pins with stronger balls that are just smooth and arcing. Right now what we think will work best is the Sting, Nasty, Jacked and Jigsaw Corner. Jigsaw corner more for people with less hand. For the Sting the MB at about 65-80 degrees to decrease the flare and smooth it out. Hope this answers your question, if you have anymore feel free to ask me.
Jbuzz - Right now we have a red Jacked that was the original batch color before they changed it to purple. We also have a overseas Widow Spare that is red/black. We might be getting a couple others in soon, not positive yet. If you check out our Facebook Fan Page (The Hammer Booth) you can see the balls we currently have as well as any future balls that come in.
Getoffme - I think your idea for the Black Widow Sting is a great idea for the team event to start. Once again it all depends on your speed and rev rate, but from what we have seen it looks like this is a safe bet.
