Hi everyone just looking for a bit of advice, my hedgecutter is due for a change at the moment I was maybe hoping to buy a 6570t but my dealer sold his last one a few weeks ago but he's getting in a new model 6572t, is anyone running one of these, is there any difference? Also I was thinking of getting a hydraulic roller or an orbital unit on the head anyone have any experience on either of these which is better, thanks
