I've been using the same Tor 50 for 5 years now on the kite and probably done in excess of 200km of drop and retrieve.
The reel is smooth and works just as well for fishing, casting and kite drops.
One must tack and set the lift on the kite to maintain no more than 4kg of pull but I prefer 3kg and at that you just reel away.
One should never sukkel with a kite when retrieving it, if you do then the kite is not set correctly.
40cm Storm kit for wind to 110km
65cm High wind kite for 25-60km
1m for low wind of 12-25km
Enigma...are you using an anemometer to measure/gauge the wind speed?
where can one obtain this?
