[ But anyone who wants to know the official, straight-down-the-line Shimano spec can go to the Shimano website and read it off a chart.
Within the context of the original posting, I was of the impression that the user is fairly new to bike fettling and - let's face it - finding your way round the Shimano web site isn't particularly non-bike-shop-employee friendly.
My take on the original question is that REKI seems to be fairly new to this and wanted to use this combination for an important ride, at short notice. Any "fettled" combos really need to be run in for a bit beforehand, to be on the safe side, unless you really know what you are doing.
If we'd all followed Shimano spec, we'd never have found the hidden click in our XT thumbshifters or put Ultegra freehub bodies on our XT hubs.
As if anyone would be daft enough to ever try something that.
(you peeked at the photos of my Dynatech MT3 didn't you. Oh bugger - don't tell my boss.)
