training is possible but when running horizontally the growth looses steam and will concentrate at the highest point. ive been trying to train over an arch for a few yers now with limited success, tlast year the arch collapsed with the hop mass while the end trained along the fence for 2-3m was light in hops by comparrison.
i have seen the idea of running cord off a short 2m pole thru an eye at the pole top which allows you to drop the string by a meter or so when the bines grow to the top which you can repeat as often as necessary while its growing for a maximum crop. they can grow 6-7m up
unless you used a drop string the maypole could result in a huge mass of mixed hops growing on the pole top tho. ok if you like hop surprise brews, but a pits if you want to differentiate between varieties
