What we do in our pack is to swap out the necker and slide at the last pack meeting of the year. We are upfront about this when boys register that we provide the initial necker and slide, and then at the end of the year we will do a necker and slide swap if they have one. No wolf slide, then they get no bear slide, no wolf necker then no bear necker. This way we are only, as a pack, spending funds once per boy. We have the amount for the first necker and slide built into our initial registration fee for new boys.
