Nedley;

Do you stay up at night in order to make the every 30 minute search?

Also, hate to be the bearer of bad news, but the 20 is probably a slow shipper. The 7 is much smaller and seems to just Jetstream its way to home base. The 10 is a little larger, and little slower. Alas, the 20 is bulkier, heaver, and more noticeably by all those handlers who want to see what's inside the big box. It could be worse, you could be waiting for a 30.
