Does some type of waist support exist for Shoulder mounts?

[Richard J. Johnson]

I have a Red Rock Shoulder mount that I just can't use on my shoulder. I am 6'7'' and really can't bend over for take after take. Does a support system exist that has a waist band and some sort adjustable arm that comes from that to take the weight at lower heights.

I found this, which would help but I'm not sure how low it go and how durable it is. I have not found anyone who owns the thing..
