AHE seems like a good place, but they're out of stock on cinch buckles. I was leaning towards decender rings as I thought you can use them with both cord and webbing unlike buckles. If buckles can take cord too then I don't know!
Are there any UK based shops that sell kit. I've bought from the states but recently I've been stung by some pretty hefty import duties.
Do I need a continuous loop to attach the buckle to my hammock biner or can it go straight on? I suppose with the loop it'll act as a drip catcher too?
