Used the block again today, so fast, smooth, and easy.
I use a basic old school rope snap for 'knotless' rigging attached with a bowline to the 1/2" bull line. Combine that with a block up top and 2 steel rings anchor bended to 3' of 1/2" line for an excellent redirect that passes the rope snap through it no problem, it is a supremely simple and effective set up imo.
