While I do not endorse thegrip, it CAN hold a great deal of weight as shown in this picture which shows a guy using it to hold 40 lbs. I personally do NOT advocate using that much weight.
The other picture is the tripod from trac-man.com (stretchwilly.com). I was going to ask what guys think of this product, but the websites as of this writing are not working. Perhaps this company went out of business. The owner/inventor (Ken) of the trac-man.com originally went to Dr. Reed, lost length, and then went to Dr. Rheinschild for
Revision. This is NOT Ken Beaton.
