my opinion is that before you can feel the trim change due to expansion or contraction you will be flying much more complicate planes than a four star 60.
But I am in belgium and here the temperature variations are not enormous, I have to admit that.

four star 60 is a serious bird, to me wood pushrods are good for low speed planes only , not for a 4*60 because they flex easy switch to fiberglass or carbon fiber.

I succesfully use wood dowels on planes like a kadet senior, and I don't have anithing against them, but on a 4*60 I think it's not judicious.

That's my opinion only
