Learning Doubles on Stepmania

[ddrmaniacaaa]

I know there are a couple of you who have mastered doubles play on Stepmania. I am just getting started. I have incorperated an 8 finger spread setup to try and neutralize one finger per arrow.

It goes something like this

Left pad
left-w
down-e
up-r
right- space bar

Right pad
left- right arrow key
down-numpad 7
up- numpad 8
right- numpad 9

digits i am using go in order from left ring finger to right ring finger (ring,middle, index, thumb is on space bar, right thumb on right arrow, index, middle, ring)

Has anyone had success with a similar setup or can tell me a better one? so far I can fc light 1 and 2s, but have only been playing for 2 days? did you find that you had to relearn everything, and does this affect your singles play at all? thanks.
