Thanks for the reply Drones33
Your post is extremely helpful and you have given me a bit more to think about concerning the skin. I would like to be able to wear the jacket for as long and as often as possible, so I think I would prefer it to be on the lighter side but able to have layers under it for winter. How much heavier is cow over lamb? A yellow-ish Lamb would be disappointing, so that is a concern. Does Pecards work on Lamb too, or is it just for cow hide?
