look forward to it.
That copper ring around the holes is very narrow, unless you have  
throughhole plating
you'll have a hard time drilling and soldering, and getting mechanic  
stability.
Oblong pads help a great deal.
I also noticed drilling is easier centered if you only leave a  
smaller-than-final hole on
the transfer.
