I am getting set up to work on a ton of bows.

 

i was looking on riogrande.com at their silver choices for lapping.  I was first trying to decide between fine silver, .999% and sterling which is 92.5%.  But then I came across Argentium which is 93.5% silver and is tarnish resistant.  

The other thing I am going to order is a cheaper silver colored wrap and I am trying to decide between German silver which is a nickel based alloy,(no actual silver) and silver plated wire which would tarnish like regular silver.

appreciate your opinion on both

The decision is largely dependent upon intent.  If the wrap is being done based on mechanical properties, go with silver or one of its alloys because it is 20% heavier than nickel.  If the wrap is being done based on appearance and cost, go with nickel because it does not tarnish and is a lot cheaper.  Both metals are easily wrapped and soldered.  

If you are planning to avoid solder and are willing to use silk thread to tuck the wrap ends under itself, keep the wire diameter under 0.004 inch.
