Nice bike, I’ve the 2005 version. Recently went from 130 Revs to the 150/120’s like yours, great fork. The bolt through and black box damping are great compared to the 130’s and Q/R. Anyway, at the same time I also swaped to low rise bars (from mid-rise), took out the stem spacers (at least 10mm IIRC) and fitted a zero rise stem. With this, my riding position is approx. the same as before, so I mostly leave it at 150mm and climb at 120mm, like you expected. Looks like you could do the same, from the photo, if you wanted. Static head angle at 150mm, hope headset, is 68 degrees according to iPhone clinometer app.
