Sweet pics Butch... really love that flying sawdust effect...
Hey ... who says you're not progressive.... those ugly gloves are the way to go IMJ... so that's very cutting edge of ya....
I have never choked a sling through its eye before... always keep both eyes on the hook and use a shackle to choke the doubled sling on the tree.... which adds plenty to the SWL of the sling...
Too bad Nick couldn't make it down to see ya.... He'd have changed your life...... If you were using a split tail... you could choke off the climbing line to the tree and run the friction hitch on the single SECURE line.... Saw Chisholm demonstrate that years ago.... no need to untie and retie the friction hitch. And if you added a rope guide, friction saver, you could come down to your next cut on the climbing line, then lanyard in and reset your new tie-in in a matter of seconds...
I guarentee if you'd see it done once like that you'd never go back.
Food for thought!
