If the Niner feels better to you and the extra $$ is affordable and doesn't put a big strain on your finances, go for the Niner...or you will always wish you had.Its not that I don't dislike the trek.....I found the Niner to feel better cornering. In comparison the Niner felt more natural and flowed better. The niner seems to feel more like it can blitz through the rough with more confidence. As for the place I did the demo my most local trails are more xc oriented with roots, that's why I ask about suspension design. As the trek stands now I want a few upgrades that are stock on the Niner. Those upgrades total about $400. That pretty much brings the difference to about $1600.
