Is it going to be a shaver or just a looker?
I would mock up scales in wood or plastic to see how they feel in the hand. It is not just about weight, thickness at the pin and width of the scale in the hand make a big difference in the feel when you shave and strop as does the weight.
Take a look at the AOS Stainless scale TI and hold it in your hand and see what you think.
If it’s a looker it does not matter.
All my lookers are shavers.
