An absolutely fabulous tool which I credit for finding 4 operational upgrades this year for me already. In fact, since subscribing I have had 2 r/t to Asia all operationally upgraded. If I continue to be a little flexible on the dates and routings I hope to have a few SWUs left over at the end of the year. ^
