its funny, i have asked the same question on the mtbr forum 29er section
had totally mixed opinion there too
generally people who have adjustable posts (though not all) advocated getting one, those that dont have one say its not needed
i will give riding with the saddle at correct height another month or so (just dropping for technical bits
if the raising and lowering is doing my head in then i shall look at this again, have also been told that Giant are doing a similar type of post soon, so more and more options on the market.
