I kinda like the post in here explaining a custom progression scheme...

like this:

0.1, 0.2, 0.3, 0.5, 0.8, 1.3, 2.1, 3.4, 5.5, 8.9, 14.4, 23.3

He added the previous 2 together to come up with the next progression.

P.S. If you looked at my setfile I am merely using doubling currently to see how long it takes to Blow-Up (I consider a blow up 9 trades with 1K initial) ...but this may be the more conservative approach above with 12 possible trades.
