Jobst says to run the pulling spokes on the outide of the flange because the spoke will be pulled in (straighten) during pedaling and increase clearance. (p. 74).

This rationale is laughable. Firstly a setup that needs this clearance "trick" has a spacing problem - fix it. Secondly if you need this "trick" you would jam the derailleur into the spokes upon coasting! Ouch! Thirdly the spokes in the derailleur "interference" area are generally detentioned. (p. 19 and fig. 8) and its hard to say what the relative movement in and out is. This is especially so because "spoke line" problems on outside spokes can cause a detentioned spoke to tend outward.. (p. 103 and fig. 51)

However, should you still side strongly with Jobst's argument and feel the risk of incipient jammed derailleurs warrrants, feel free to send your inside pulling spoke laced wheels to me for safekeeping.
