Johan,
What is the weight limit for the glider ?
ΚΑΛΟ ΜΗΝΑ.

EXAMPLE:Take off weight = 75-95 kg - ideal weight = between 85-95kg
Pilot (+clothes, shoes, helmet ...) = 76kg
Glider = 4.85kg
Harness to sit in (inclusive reserve-parachute)= 5.15kg
Rucksack = 3kg
TOTAL = 89kg = OK
If the total weight is 75-80kg, you fly longer, higher but the risk of collapse canopy is also higher (in turbulent weather)
Standard gliders open again allmost automatically, is not a real problem, only high hart beating

If the total weight is 95-100kg, no problem, you fly more stable, but more difficult to gain height and you fly not that long, easier descend.
My friend-pilot from Patra is Greek champion, weight 115kg "nude", but he has appropriate glider!
So, no problem; if you want to learn
