Thanks! Definitely overkill, but I use it all! I've been using Helix since very early on and this arrangement has kind of developed over time. Helix handles amp, cab/IR, dirt, modulation, and tone shaping (eq, compression). Reverb and delay is handled by outboard pedals in the loops. The music I play lately is very reverb-and-delay intensive, and I like being able to plug in exactly what I need or want. The Freq Out is a "toy" that doesn't have a counterpart in Helix, and the Boomerang has functionality that is critical to what I do and that the Helix looper doesn't have. The Helix's ability to seamlessly incorporate outboard gear was a big part of why I chose it when deciding on a modeling platform.
If you are interested, this is the sort of thing I like to do with all that stuff:
