Can someone comment on the improvements/changes that they have made to the power pole designs from 2016>2017? I know that they went to hydraulic hoses instead of tubing and the pump got smaller (supposedly stronger) and all models are powder coated not annodized. Normally I prefer to buy the end of a products model life instead of at the beginning since all the bugs have been worked out in the old and new bugs tend to be introduced in the new ones. So if anyone has personal experience please comment. I can't tell how frequently power pole changes their designs, maybe they are like cars they just like to tweak them every year.
