IMO, this is the way to do it. Replicating a sound with the Helix forces the learning curve. It also makes you learn to dial with your ears and not your eyes. It's one thing to lay down a certain pedal model and certain amp model and expect a certain sound. It's another to have a reference sound in play and dial to capture that sound. You'll learn there are multiple paths to getting there and sometimes you'll discover a better way in the process. If I remember correctly, you said your base sound with Vox + delays. To me, that's very doable in the Helix. Now if you said your base sound was a Freidman BE-100, you might want to look elsewhere as that is not represented in the Helix, at least at this time.
