If you like shoulder rigs and they work for you good luck. I've tried to like them in the past and just couldn't. If I would try something close it would be an Alaskan chest rig.
Update: after my comment I just made i decided to order a DD Alaskan chest rig for my Dan Wesson RZ10. I've been considering it for quite some time. I'll try to follow up with comment on how it wears.
