Hi Dave,
One pump system, works well. Pump the kite only once. If you pump it more than three times it will void your warranty. Close off valve, attach lines. All C kites now come with a 5th line, so if your old 09 kite doesn't come with one, you can but an after market modification, called a bridle. This is then connected to the trailing edge, to assist with relaunch. Place kite in normal position in c shape, run upwind for about 300m like the kids do to launch their triangular single line kite, and watch the kite launch off. Ensure that you wear your boardies over the top of your wetsuit, complete with a bonds tank top.
If you PM me i can send more useful hints ant tips.
Welcome back to kiting, and hope all goes well tomorrow.
