I had a hard time beating xortex and slingshot so i switched to a pre hands on update version of the lab and it made both alot easier.

I'd have to do some more research into the Hands-On update before creating new categories/variables. For now it doesn't matter which version you use (for example, the current Slingshot record was made before the HO update). If I find the game-play is significantly different then I might separate the categories.
