Did I send you one of my "balance retainers"? It is a snap strap that goes around the handle about four inches or more up from the ricasso and dramatically helps to balance out that heavy handle. I discovered this in the past few months so you may not have one. I have a pic somewhere, I'll post one when I find it.
Another thing I've discovered that helps a lot is getting the strap to cinch up firmly around you. It makes for less wobble thus more comfortable wear. Another recent epiphany.

R&D has been wonderful in the last year, the HOGS have been very fourthcoming with their reviews and testing on the Dundee rig, and thats helped all of us sheathmakers improve our product. I've worked especially close with xaman on the Dundee rigs as he has asked all the right questions!

Thanks Eli and all those who have helped out. I know we will keep improving and adding to the rigs to make them work as I feel its one of the best ways to carry a very large blade.
