We’ve been using the big Omni in the span with a quick sling. We use at least 1 big DMM Impact on the moving side down to the GRCS...often multiple blocks on the moving side and multiple redirects on the stationary side so we can go BIG!
My only gripe with the Omni is when the “brush” or “wood” won’t allow proper orientation. Everything runs beautifully until you want to lay the piece down and suddenly the rope won’t run fair through the sheaves. Those are the only instances where I would prefer to use a ring/dead eye.
We’ve been spanning for several years, and the greatest addition to that kit was the Makita Hole Hog dual battery right angle drill. Sometimes we’ll put a stay on really horizontal leaders to the hinge won’t break too early, but WHOA MAN can you really swing some wood around with that set up...and FAST! Lifting logs, hanging half a tree, you name it.
