Thanks for the responses, all.
Gunpointmetal, I think you're correct in assessment. I usually use my amp as my monitor and let our sound guys worry about front of house. I think because I was relying solely on the house system, I was experiencing some delayed bounce without the immediacy of having my amp behind me. Hopefully, I can have our sound company provide an extra stage monitor so I can gig without an amp completely. I've looked into getting an FRFR, but if I have to carry a speaker, I figure it might as well be an amp just in case something goes awry with the Helix.
