personally I wouldnt recommend the M80
but yes a 7m would be a good size for the lady
for you your probably looking at a 12m
try find a decent kite that is going to give you a good wind range
something like the north rebel (there reasonably priced too)
depends where you are over in WA i guess. I know fulltilt is a little south of perth
but thats about it. ask around cause im sures theres plenty of spots
you could get taught
