Does anyone have personal knowledge about the durability of artificial slate sold under the trade name of “Authentic Roof” by Crow Building Products or “Dura Slate” manufactured by Royal Building Products?
If you’ve installed either of these products on roofs with valleys, how have you held the inevitable small triangular piece in place without piercing an open copper valley? Thanks

Don't know about the durability of those products, but I've used a piece of copper wire nailed to the sheathing beyond the side of the valley copper to hang the little pieces on. Apply a little dab of high grade caulk (Geocel for example) underneath each piece to keep it from swinging on the wire. I've done this with tile, but it should work for fake slate as well.
That's similar to what I've done with real slates.
Take a copper strip ( you've probably got access to some scrap, I know) about a half inch wide and ten inches long. nail it in place, overhanging the valley so that the battom of it is about a half inch further down than the slate will be. Place the slate with a dab of caulk to achor it and then bend the tail of the copper strip up over the bottom of the slate.
Works same way for patch replacements..

Yeah, Piffin, that's the way I replace field tile/slate, but the original question was about those little triangle pieces that inevitably occur at the valley. The bottom edge of the piece is parallel to the center of the valley. The strap method could allow the small piece to slide down hill on a steep roof unless there's some other trick to it I haven't seen.
Between the dab of caulk and the edge running into the adjacent tile with a W style valley, it can't go anyplace else.
The wire trick is probably beeter though because the tab can hold onto debris in the valley..
