I've been using the Raid Braid you sent me on my
SEI for a while now, and thoroughly approve.
I’ve used it as the main halyard on a 107 sq ft balanced lugsail. The boat being 15 feet long and quite stable puts a lot of load on that line at times, and it's performing well. Elongation under this load is minimal, not at all noticeable, it's very easy to handle and— in particular—wraps around the cleat and hold better than the stiffer rope that is common in this size. It also looks nicer on my somewhat traditional boat than the brighter colours, and its very easy on the hands.
Ten out of ten!
