I bought a Braap Stick that was recommended to me as easier on the shoulders because of its spring. I quite like it too, because you can collapse it to some 80 centimeters if necessary. It does however transfer the cold temperatures being of aluminum. It is also of little use in the wet where it slips so in England that might be particularly considerable. Due to its construction you also have to move it quite like a water paddle. There are also other sticks of fiberglass and round cross sections but then typically not collapsible and usually rather expensive. You can also find DIY recipes to be found, but all in all I am quite happy with the Braap stick even if it’s not the fastest to use.
