If you are looking for something more solid than what you have, I wouldn`t go with LOGR. There are lots reviews on them, some here, some PS, and all kind of agree that they are not made for daily wear. Good for an occasional wear RHR, though
I haven`t worked with Amcor, I have with DK, and his work is solid and substantial. My solitaire from him was 8.3grams, and my simple 2mm band was 3.5 grams.
