One thing operator, please could you do me a big favour and check the chainline of the inner and outer ring positions on your setup?

I.e. with the 7410 BB and matching 7410 cranks. I don't have the BB so can't, but would be very keen to know where the cranks sit on them so I can change spindle length/taper appropriately. The figures I've used so far (41mm inside and 46mm out), I've just taken off Sheldon which says those are the Shimano Road Double Standard, into which category I assumed FC-7410 fall. That might be what it's meant to be, or not, but either way I'd be keen to find out in practice where it sits/chainline.

Thanks for the other posts, haven't got time to digest them just now, I'll try and do so as soon as possible.
