nah. i tried an experiment with a 29er rigid fork and wheel up front a couple years back when in colorado, that more or less replicated the geometry of the pike/26er front end angle and height.

the steering with the big wheel blew goats, particularly on the tight and techy trialsy stuff i like. and that was on trails with less of that kind of stuff than around where we live.

no real interest in the 29er thing otherwise anyhow.
