Double rope bridge

A Dyneema core on 10mm cordage is ridiculously strong but becomes vulnerable to UV damage and abrasion when the polyester cover wears, which is why the Globe 5000 is not recommended. As Arlo points out, with regular inspection and replacement the thinner cover on the 5000 can be monitored and "danger" mitigated. I've already posted in other threads about making my own bridge cordage combining the very durable (a little more robust than the stock TM bridge cord cover) polyester cover from 10mm Sterling HTP and a stripped Dyneema core from a sailing line. To quote Eddy Vedder, "I'm still alive". I've got a double TM bridge set up with my custom cordage and it's holding up great. As splicers know if you want to build your own hybrid cordage you need to pay attention to core/cover fit and do a good job balancing the core and cover before tying off the stoppers and stitching.

Teufelberger has splicing instructions, why not sewing instructions for the bridges. Are their current recommendations based on concerns of safety, or on greed?

Splicing is mainstream, hand-sewing is not. Remember when Kevin Bingham was working on getting the Rope Wrench accepted for ISA competition? Uphill battle for sure. The increasing acceptance and use in the climbing community forced the ISA to take the wrench seriously. Hand sewing PPE will likely never go mainstream ;-)
 
I believe that splicing has become mainstream because the manufacturers put out the instructions for individuals to do their own. If bridge end sewing instructions were provided by the rope companies sewing would also become mainstream. This type of sewing doesn’t have the complexity of splicing, or trying to hand sew eyes, so why aren’t instructions provided, again is it really about safety, or them making the money?
