HOw to get the right chainline with an Alfine 11?

Just in case STW doesn't get me an answer, does anyone on here have any ideas, please? The situation:
A question for folks running Alfine 11 rear hubs. What set up, particularly cranks, axles, BB shell width are you running to get a workable chainline?
IIRC the Alfine is supposed to have a chainline of 41 and a bit mm. I'm trying to get as close to that as possible, assuming it's necessary. Tried a couple of cranks / BB / axle combinations recently on a frame with 68mm BB shell and they don't look right:
Would really like to get the RS8s to work but would happily settle for getting either of the two (don't want to buy more cranks) working.
- Shimano XT octalink cranks on a 113 axle - inner tabs/ring seem to line up but that would mean a pretty small ring which I expect would give poor gear range.
- Middleburn RS8 on a 118 axle with a two ring spider - rings too far out from frame, whichever tabs used. Cannot flip the spider as it's machined to only fit one way.
If you're running it out-of-line how are you finding it?
Also, what chainring / rear sprocket are you using?
