Being a recent convert to german bow I have a fairly decent pernambuco french bow (30 year old Winkler valued ~$600). My German bow is an Ary 400 brazilwood. It's not bad, but the Winkler is a better stick. I don't have enough money to buy a good german bow, right now and I've heard that the resale market for $600 bows isn't all that great. So I have this hair-brained idea to outfit my Winkler bow with a German frog. What do you think about that? What are the issues?
