you are correct that the ziptie will not with with an HP, but it will with an HPx.
however, in the original post, i was referencing the HPx. since the umbrellas are easy to find, this might be an easy way to put an HPx on your frame's top tube or seat tube without having to use a pump peg or that special Zefal plastic mount above.
