Hey Ems,
Both Netty and I have gone for the Julius k9 power harness in orange.
http://www.k9-product.com/indexpro.php You will need a size 0 or at a push size 1 for Pops and Jasper. If you go to their website you should be able to get a local shipper to Cyprus as they are a European company. I think they are brilliant, Woodley really works well in this as they are so comfy and help slow them down a bit too.
In terms of long lines, Netty has a fancy leather one that doesn't get tangled and I just have a standard 10m one from my local pet shop. Both seem to work well, I actually like the fact I have been able to put a couple of knots in mine as I can hold on easier.
I have been reading some good papers, I'll send them to you.
Go go spaniel noses.....
