Can anyone give me some infomation about the above NDT's.
I am currently on Armour but is very expensive, have found Erfa cheaper in this country but I am worried that it will not be as good?
Have others found it to be the same strength grain for grain?
Would you just switch from one to the other?
As you all can appreciate when feeling better you don't want to mess with it but cost is obviously an issue long term.
