You wouldn't be able to get enough halyard tension in the lowered position , thereby not be able to depower the main as much as downhaul,outhaul and rotation all ready allow. There are many posts referencing this.If it gets so hairy that I need to reef the main ,it comes all the way down. This has only happened to me a couple of times.
