Quoted from Rum-Z:I like Cliffy's. Cliffy's are thin, but if you have an area where you're getting deflections of slower moving balls, there is a trick you can do with some small strips of Mylar. You can get some 2 mil thick mylar from Pinrestore.com, and you can cut it into strips of varying widths (all relatlively thin), and you can lay down the thickest width first butted up to the edge of the Cliffy, then you put a strip that slightly narrower on top of the first strip, over and over again, until you effectively build up a ramp of mylar to the Cliffy, which makes for a nice ramped transition that doesn't mess with ball travel.
I had a thought when I woke up this morning, but isn't it possible to route some wood that's the thickness of the Cliffy? That way, one could insert it basically flush? I would guess, apart from the complexity of doing that yourself, there may be other issues with doing it that way, but it would make for a pretty smooth transition I would think. In practice, I won't ever attempt that 
Only place I could see that working well would be an OEM. Also disclaimer: I'm new to pinball collecting and don't have a machine yet, and it's before coffee - so this is probably a terrible idea
