Suitable line weight for Conyne-Delta 60"

[bobc]

Hi,

I've had 50# line on this kite for a while, but haven't flown it for a long time, so it's badly deteriorated. I'm starting to play around with lifting very small rigs for KAP, probably no more than a pound of so (old iPhone, maybe a GoPro). Should I be using heavier line? The kite has a lot of pull in good winds - though likely much less than it seems - and I'd hate to lose a payload.

 

Thanks
