This is a really good question that comes up a lot on here. There are some very good threads from over the last year, especially during the summer, with all the answers.
You would have to do a search on Piggington….
The bottom line is you should still wait. Another 6-12-18 months is not going to kill you guys.
If I can recall the names of the threads, I will post them, but you would be very smart to wait a little longer.
