In a word, no. I did around 5 hours there working on belly, back & an attempt at sit flying. In the end, after a couple hours practice and wearing 2 suits for extra drag, the only way I could get my 'sit' off the net was with a weird hybrid of sit & back flying.
Having said that, it's a great way to sort out the basics of freefly before you go and jump in a tunnel at $900/hour in the US. At KL you'll get 3 hours for that price.
