Very nice!
Was looking at that course myself but I haven't pulled the trigger yet.
My wife used to give me a hard time because I used a wireless. She'd say stuff like, "you're only two feet from the amp", or "it's not like you're running around on a stage". So I stopped using it. Then one day she was in the music room and stepped on a cable and it rolled under her foot. She didn't fall, but did lose her balance and almost fell. I now use a wireless again, and she says nothing about it.
You're going to LOVE wireless.
