Modeling isn't for everyone, it can be a little daunting at first as there is a learning curve, but the Helix is designed for mere mortals, and you will most likely find yourself wrapping your head around it soon enough with some initial effort. After that point it becomes very rewarding! As you design your presets at home, you will get better as time goes by at anticipating what will work once you hit the stage, regardless of what you are using to monitor them. The advice already presented here holds though. The closer your volume is to performance levels, and your monitor equipment is to a PA speaker, the more direct the translation will be, and more likely fewer preset adjustments will be required for that transition from home to stage.
