with a 10 you may cover everything
in the morning it is generally 20/22 knots maximum, and you can always stay in the centre of the lake where it blows a bit less
in the afternoon it generally reach 15knots, so you MAY be a bit underpowered with the 10, but many people use it as well
my suggestion is do the lift from Navene in the morning, at kiteschoolnavene (no other way to do peler than a lift, and you will love it), in the afternoon leave again from navene. it is very funny, you enter into a small tunnel to lift the kite

the association of navene cost much less than the one in Campione, and it is very easy to join

it is positioned in front of hotel eden
it cost 15eur, and then 10eur per day, unless you make a weekly package
lift cost 30eur
if you have to choose, ride in the morning, it is always much more fun in my opinion, and the panorama is stunning
bring a full wetsuit in the morning, in the afternoon you may use a shorty if you're german, but I still use a 4mm (outside is super warm, but water is quite cold still)
no place at all where to tetheror drif launch
have fun!
