To play Devil's advocate for a second, there's some evidence that Enochian's not even a natural language, but was contrived by Dee. In some ways it has more similarities to English than anything else. If you must use Encohian, I'd just pronounce it anyway you think best. But there are good reasons to use your native language.
For example, if you wanted to communicate with an angel, why wouldn't the angel be able to understand your native language? It is an angel after all. And if the angel wanted to communicate with you, one of two things would be necessary. It would either have to mystically make it possible for you to understand it, or it would have to already understand your native language. If it has the power to alter your mind so you can understand it, it stands to reason it should have the power to understand your native tongue.
Using Enochian might impress yourself or others, but I really don't think it matters to angels.
As far as scrying, the method I like best is a black mirror. You spray a piece of glass with black paint then after it dries, put it in a frame. You can decorate the frame in any number of ways that suit you.
