Really can't say enough about these draws! I was quite anti-Madrock until these draws. They are stong, light, have a rubber piece to hold the rope end from turning round, and most importantly they clip like butter.
I'd like the dogbone to be a bit more substantial, but I'm pretty sure thats just a head-game issue. They are plenty strong.
Wild Country has a similar product, however I much prefer the Madrocks.
