You've made 2x huge changes in one go.
It's taken me most of the year to get the best from a move to 29ers.
I can't believe the difference it's made to evey ride.
But I tried a CF rigid front end and saw no benefit what so ever.
Then I asked myself: Why run rigid forks?
Now have an 80mm Fox front end from eBay and it's a delight on every ride.
Ditch the rigid forks, they'll give your body a work out / pounding you simply don't benefit from in any way, you'll be slower on anything rocky or gnarly or bumpy in fact anything XC (!), your shoulders, hands, wrists, chest will not thank you at all for the pounding you'll be receiveing.
Unless you ride very smooth trails then get them on eBay asap and do yourself a favour!
ps - I only spent one day, 6hrs, with rigid forks on a magazine shoot and never again. On the 2nd shoot we were shod with suspension on the front end, and that's all the experience I have as such.
But welcome the world of 29ers - prepared to be re-engaged by mountain biking as you'd hardly credit it! Every ride, every trail is like riding it anew. The other tip is RRalf 2.25's a revelation, huge, and they look clown-esque I agree, but brilliant.
