Thanks for the tips stroke and John. Really helpful, I've linked up with some guys but unfortunately, differing schedules have made it very tough to meet up regularly, so I've basically been going at it solo since the first meetup. I've checked the line equalizations and stuff and upon further examination, I've found that my handles do tend to sag - I move them or position them like that without thinking. I haven't tried the De'one guys, will try to look them up. Also, no worries about the subscription John, thanks for your help!
Also, stroke, you mentioned that when the kite is going into a fall, I'm supposed to 'give', that is, I should be moving towards the kite and tyring to keep the lines slack right? But the kite would still land somewhat 'hard' right? But I guess, not as badly as when it's being pulled out the sky in panic.
Nearly forgot, I bought the JB series so it's got the handles with the adjustable knots. I've been flying using the outermost knots.
