I was really after an Angeltails ring sling because they look so gorgeous and have the SBP shoulder but it seems that they are no longer made. I've found that Rumba Lucia will custom make a ring sling with an SBP shoulder for me and am considering getting one. Anybody have any experience using Rumba Lucia? They seem fairly reputable and good quality plus I'll get exactly what I want but thought I'd check here first!
