Before the symposium I put an eye on a new 1/2" arbor boss line, turned out nice. Nice rope for the price too. My wife wanted it for her own line, pretty colors. Now I can say, I don't just trust my splices with my life, I trust them with my wife! See what madness home splicing brings!
Seems to me like a good sling eye to eye. I've been using the miniature version out of bluestreak when we made our friction savers but I already used up my ring allowance on 3-strand. Quick redirect for light rigging with a steel carabiner.
I'm into end for end loops, seems for crane picks a loop out of 5/8" would get you more mileage, especially if you're chokering the load. I'd guess (easy for me to say) that the same method and measurements for an eye splice could also join the rope end for end, no?
