"Hi - looking for a bit of advice
The kite got through the loop but was way below me, basically felt like it just didn't come back up to catch me at all and I ended up dropping onto the water from about 15m any idea what went wrong or just a bad idea to go for it?!"
My 2 cents worth:
What works for me: Shorter lines can make it easier to kite loop ( 25m 17m 15m )
Go high with speed keeping the kite forward to get forward momentum to cancel out the back loop, at the top of the jump commit and yank a back loop, try to land with the kite directly above you, you may need to turn the kite down after to loop to soften the landing. All kites loop differently.
If your kite is below you after a loop, your not looping the kite right, you might be looping too slow so the kite goes under you but not back up above your head.
What i see happen often is: Some people half loop or don't loop evenly through the loop, they hard pull first half of the loop then freak out and only partly or softly pull on the 2nd half of the loop, making the kite dive down but not come back up.
