Wow, this topic has come along at just the right time for me, I've got three EO 6's on the way and want to make an active train with them

It's answered all my other questions about swivels and attachments etc, but I've just got a newbie question about what line strength I would need for the primary line. For a single kite it comes with 20lb line, so I'm guessing that with three on there I'd need at least 60lb? Is that about right or is there some weird aerodynamic law i need to take into account when their bouncing all over the place

I actually wondered if I'd get away with using the original 20lb line, but that didn't seem like a good idea...
