It's all about using the tension of the Tbar and popping into the rotation. It's actually easier than you would think. Although, most hills hate people fucking around like that on their tbars.
poma lifts are fun af. at killi i was lapping mouse run with a poma and rode up switch and did butters over little nulls on the lift line. lift attendents either didnt care or couldnt tell me to stop due to the fact they hardly spoke english.
