Hi there electricd,
At 105 lbs (46 Kilos) in 5-20mph winds (4-17knots), you should look at another sport for winds below 12 knots. Maybe landboarding with a kite??? Have a look at our website for ideas and then try and find a local supplier for MBS or Ground INdustries mountainboards. Take a look at Ozone Access 2 XC kites, probably an 8m for you.
For the few knots above 12knots and below 17knots, for your weight, I would recommmend a 10-12m kite. A board will be a problem for you being so light, but something around 128 x 36 would be good.
Most kite company wind ranges are based on a 75 kilo (165 lb) rider so they wont be any help to you in any case.
I would recommend you call up a good local school, do a few lessons, then ask the instructor what they recommend for you. They will know the best locally available kites and also the local wind ranges and places to kite.
I hope this helps you. Good winds,
