International Shipping - FedEx (yeah i know...)

I realize most people use USPS for shipping from the US to Europe (probably belgium). I'm considering using FedEx due to a pretty decent discount. Few questions before I go through with it:

1. Looks like I can have the tax/duty/fees billed to my account which is fine. How can I minimize this? The duty/VAT is based on the customs claimed amount right? So I'm assuming I make this low and claim it as 'collectible glassware' or something of that nature.
2. Are there any known problems with doing it via FedEx? Anyone know if fedex INTL packages all get x-rayed?

I'll do it USPS if i have to but I'd prefer fedex due to the better tracking and speedier shipping.

If this was answered in another thread, please link me. I saw quite a few threads but everyone ends up recommending USPS and I would like to hear from someone that has used or does use FedEx for US <-> EU beer shipping
