Hobbs is bomber, short lifts or taking slack out before blocking. GRCS is limited, you can drop chunks on the bollard (like you should instead of blowing it up like rico

). The capstan winch is exactly just that, a winch for lifting, basically static loads.
IF your lifting with the Hobbs I'm under the impression it really needs two on the ground. One to lift, one to tail.
I do ALOT of winching, I bought the GRCS and have yet to use the bollard. I've lifted whole trees solo, Pulled trees over backwards with it, solo... There are some tricks to set it up by my self..
Now that one in Japan looks badass, hollow bollard with the winch inside.
