9'6 Dunks

Here are some recent dunks I've done at 9'6. 10 months ago I could barely dunk with 2 dunks. I could get a few down but they were very weak and could hardly be considered dunks. I've just recently started jumping again since the basketball season is over and things are slowing down school wise. Also I just started on trying to get dunks off the lob which I'm doing pretty good at 9'6 now. Starting to jump more off of 2 feet to save my left leg from shin splints. My technique sucks I know. Kind of scared to go fast on the street because I dont want to slip and fall on the rocks.
