...as opposed to folks like me who just think they are unnecessary in the first place. (but I don't aid)

Old news. But definitely worth repeating as we still see lots of climbers using the things.

I know it's old news, I just thought it was a good link for some non-believers to hear it right from a manufacturer's mouth. Like you said, using a daisychain to anchor still sooo very common and being taught to noobs every day. If just one person benefits from my employer's generous sponsorship of my web-surfing time today, then it's all worthwhile.

I have never understood where, how, and/or why daisy chains made it into the trad world from aid climbing. They have a specific purpose, and it ain't an anchor system in normal trad systems. Probably a good heads up for those new to the game. You don't need all this shit. The simpler the better.

The n00b I was am used these for the first couple months of trad climbing. Now; I clove hitch into the anchor, then from there, clove hitch a second time with a second biner. I trust the rope enough to climb and fall on it, so why not trust it when it runs from my harness to the anchor. As a result, I now forego the second sling/attachment to the anchor. Too much? Not enough? Edit: use proper tense

I have always felt the beauty of a daisy was quite simple; It allows an easy escape from the belay. If one anchors with a daisy, then a fall occurs and the fallen climber cannot unweigh the rope, you have the entire length of the rope to lower with+ the added advantage of being able to escape the belay by tying off,securing the rope. If one anchors oneself AND uses a daisy as an integral dynamic part of a belay- then yes you maybe a dumbass. basically a daisy allows you options if used correctly. Over the years I have come to understand that BD is not an end all, and they lack originality in thought and expression. Mario

Just because the daisy itself will survive doesn't mean that your anchor or internal organs will. Smart money says: 1. Don't fall on tethers. 2. If you think you might violate Rule 1, tie in to the anchor with dynamic climbing rope. 3. If you think you might violate Rule 1 and cannot anchor in with the rope for some reason, use a purcell prusik as your tether, which will naturally slip and dissipate peak loading.

Here's the truth about Daisy Chains: Daisy chains have always been a "personal attachment point." Daisy chains are not an "anchor" point. <-- there is a difference Daisy chains should never be used as a "team" attachment point. <-- this violates the first and second points. Daisy chains are only full strength at full length without a girth hitch. Daisy chains are very useful in many situations. Daisy chains, like all gear, have limitations. And here's the truth about all gear: All gear has the potential to fail. Any piece of gear used outside it's limitations has the potential to fail. Any piece of gear that fails has the potential to kill or lead to serious injury.

Jay You should also state that your statement is even more true with dyneema/spectra. As for the FF2... well, if that's occurring that what really should be used is an "anchor" point such as the rope, and perhaps a rethinking of one's approach to climbing. Purcell's are better than daisy's/PAS/... and they've been in use a lot longer than most think. They are really the best alternative to using the rope in most situations for the 'average climber'. I'll fully admit that I keep a daisy on my harness, however, you will rarely find me at an established crag, on a sport route, or on an established route for that matter. I use a daisy for what it is designed for, and I use the rope to tie in. Climbers need a better understanding of the limitations of all gear, bolts included.

thanks .. points - a daisy may fail at the pocket tacks .. but if its rated for 22 kn ... then it should fail at that rating regardless of where it fails ... - from http://www.caves.org/section/vertical/nh/53/RiggingForRescue-DaisyChains-2005.pdf ... where we have actual data Table 4 highlights some of the drops conducted with the Climb High 25mm Nylon Daisy Chains. While the MAF values were considerable, none of the tests failed the lanyard or resulted in any significant visible damage. as long as you clip one pocket a daisy is much better than a PAS or even a knotted sling ... and i dont see anyone screaming about those ... just use the tether to set up for lowers and rappels ...
