@BillConnerFASTC Have you been keeping up to date with GALA Spiralift's linear actuator models, the series with perforations in their vertical stainless steel bands? They've always been a unique niche product but their linear actuator series, which require zero lateral stabilization, I'm finding particularly impressive. I gather these comparatively newer models operate much quieter as well. Possibly I've been in my cave too long.
