Quoted from donkadelic:the clear doesn't dimple on the inserts because the inserts themselves cant dimple. the clear is supposed to prevent the wood from dimpling, and it's not. we're not saying the clear itself is dimpling, just that proper clear prevents the wood from doing so.
FWIW you are really wrong; not trying to be a jerk about it but this has been discussed a million times; a steel ball will win against clear and against wood. It is just a matter how much crappy wood will compress... some recent playfields look like the moon.
