What brooches do you prefer with a great kilt/fly plaid

[ThistleDown]

To be clear, I don't wear a plaid broach and have never worn a fly-plaid, but my family wore them and these are the four I still have from them:

The top left is an heraldic piece, from my great-grandfather and now often worn by my wife; the top right is one worn by a late family member and still worn by my wife and sometimes others in the family; the bottom left I inherited from a family piper (with his silver and ivory Henderson pipes ); and the bottom right is a piece of plated silver and glass sometimes worn by my father as a bit of OTT glitter (no fault him, we all do that sometimes, I'm sure).
