+! for boriselbrus. Fully up for fireroad/climb, 1" down for pumpy/techy/rolling/singletrack, fully down only for OMG proper steeps. Came from a joplin (enforced by change from 30.9 to 27.2 frame) and thought I'd miss the "infinite" adjustment, but my "mid" drops on the joplin equate to the 1" drop on the GD and it spends more time in 1" than fully down.
It takes no more than careful drilling to convert to multi (some users stick other step holes in but you risk weakening the post).
Mine's a none-remote Descender multi drop so cant comment on choice of remote set-up, but having bought a GD out of Hobsons Choice (only easily available 27.2 at the time I bought) I am very pleased with it.
