Came across this thread on the MYSWAG forum earlier today and thought it would be worth posting a link to it here. I have contacted Symon, the author of the thread, and he is happy for a link to his thread to be posted here.

Hope the content of this is of some benefit to some out there - I have found it to be excellent value. It is a "work in progress" - Symon is adding to it as people request additional info on the MYSWAG forum.
