I have a surehands lift with a sling and am going to purchase some type of hanging scale. Has anybody with this brand of lift adopted a hanging scale to use with this brand and what were your adaptations needed? which scale did you use?

At first glance I can see that the 4 points for the sling will have to be joined to a common point for attaching to the scale.

I plan on doing it from the sitting position off of my exercise table and as soon as my butt clears the table and my weight is on the scale I wouldn't go up any higher, thus keeping it safe.
