1. concentrate on a new foot forward, instead of imagining that you are riding backwards.
2. rotate your back knee out as you keep square and centered on your board, but turning your shoulders and head to the direction you are heading, driving the board where you want it to go.
3. focus on the independant movements of your lower legs to control your board to link turns
Perfect advice, I'd also add to remember to keep your weight forward.
I tend to not like riding switch the first few days of the season, but you warm to it quickly again once you get a couple of linked turns.
Once I got comfortable riding switch around the flatter parts first then forced myself to do more difficult runs switch.
Most of my mates don't slow down so riding switch around the mountain was a bit scary at times but it forced me to pick it up quickly.
