Any Helix Stadium FX would be in the same boat as Helix Stadium Rack, I'm afraid. The sell-through of both HX Effects and Helix Rack just aren't big enough to warrant prioritizing them over other products we could make. I won't lie and say I don't have full designs for both of them, but I have designs for dozens of products that may never see the light of day.
Stadium Rack has a better shot because it at least has intangible benefits like being preferred by touring artists and stage techs, but intangible benefits don't put food on the table. We gotta move boxes, and if certain types of boxes don't move, we have to prioritize the types that do.
