Have you guys seen this?

It is a series of 5 2-table SnGs First leve is a 11+1 top 4 advance to a 50+5.
It all ends at the 5 step, a 1000+65 20 person SnG with $9k first prize.
You can buy in at any step.
Sounds pretty interesting, although I have not done to well on the MTSnGs I have played (got my boat busted by rivered quads on one.)
The full structure is complicated, in 2-4, 7 to 15 players get at least something.
