Hi,
I have a post on the walls and training forum about the possibility of encouraging a more outdoor style of climbing at walls, for those that might like to. By this I mean many more foot holds than hand holds. A quick zero cost possibility would be to just grade a route as normal with a second grade in brackets to indicate "with rainbow feet". E.g. 6b+(6a).
Of course one can just climb like this already without the extra information, but I wonder if people might like this information, and if the information was provided such rainbowing might prove quite popular.
It has been pointed out to me that a training forum might not be the best place to reach those most likely to use this information, so I'm posting this here as a pointer to those that don't monitor that forum, but might like to comment:

Thanks.
