Made my own with amsteel blue from redden marine. Mucked up a good bit of rope because my taped ends were catching strands when I tried to bury them. One heads up, those individual tiny hairs that make up each strand of an amsteel braid are no joke...you can't really push through them if they snag.
I'll probably look to get a legit needle for any future splicing projects. That said, I'm loving my new setup. So much bulk removed and no more sagging. Whoopieeee buddy!!!
