Ok - lets run this as theoretical.
Assume U can handle the kite in normal conditions -
Assume this is not about a lack of competency -
this is a requirement to meet some site restrictions.
The anchor is heavy enough to not shift with say 50-60 KGs on it
1 assumption is that the safety flags the kite enough to take the guts out of the pull.
2 assumption anchor is fairly solid and not relying on being set into the ground at a certain angle but easily dislodged by being pulled at a different angle (i.e a boat anchor) .
Attach kite safety leash to your anchor of choice so it will flag the kite if required.
Attach chicken loop to anchor of choice with a weak link. The weak link needs to go before any movement in the anchor - suggest 20 - 30 kg's would be a good start.
All good?
Cheers
