OMG this BS is way too confusing. Why not scrap the acronyms altogether and just use whole words? Or better yet pictures and diagrams? Maybe hand signals or we invent an entirely new sign language for climbing systems. Perhaps we could encode the language so no-one could understand it? The truth is most people know of two different techniques - with spikes and spikeless. Let's just say what we mean and if people don't understand then a little explanation goes a long way. There's really no way we can expect the whole world to agree on what specific acronyms mean. Sorry if this is too dismissive, just trying to be realistic, FYI, BTW.
