I guess everyone has there own thing but I followed Sheldon's theory. I had a highend shop build a wheel for me. He laced it in the same direction you chose. That was my problems child. I relaced it and no further problems since. Just sayin'!
Copied from Sheldon's site:
Which Side of the Flange?
Derailer rear wheels should be laced with the trailing spokes running up along the inside of the flange. There are three reasons for this:
1)The spokes are bent around each other at the outermost crossing. Under drive torque, especially in low gear, the trailing spokes straighten out and the leading spokes bend even more. If the wheel is laced with the trailing spokes on the outside of the flange, the crossing gets pulled outward toward the derailer cage, and in some cases will actually hit against the derailer only under load.
2)If the chain should overshoot the inner sprocket due to the derailer being mis-adjusted or bent, it is likely to get more seriously jammed between the spokes and the freewheel if the spokes slant so as to wedge the chain inward under load.*
3)If the chain should overshoot the inner sprocket, it may damage and weaken the spokes it rubs against. Since the trailing spokes are more highly stressed than the leading spokes, it is better to protect them from this type of damage by keeping them inboard.
