It hasnt been available for about a year, you could use any other but some have slightly thicker wall widths, you also need one that can be extended and one that has readily available spare parts. To meet those criteria ie something that is duplicatable for others, you should look at my reccomendation (CFS 16) in this topic on Matts site, "Featherlites Merry Christmas" (see reply 3) at least until the end of the year when another "new" pole will be born and everything else will be out of date. Youn will also need the Ron Thompson pole You should expect to pay £200 for a s/h Blue Diamond
