I've been hanging with the Captain's Wench for about a month now and can't handle how uncomfortable it is to hang even 7.5lbs. I was thinking about getting a vacuum hanger, but can't really find any information on any except the Max-Vac. I was looking into the Vacu-Hanger from AutoExtender since it doesn't seem to require any pumps and is the cheapest. I hope to hang up to 20lbs with the hanger though and am not sure the Vacu-Hanger can handle it. Does anyone have experience with both? Also, I was wondering what people use for their fulcrums when hanging SO.
