I also just got a Titus Racer X after riding a Fisher hard tail WSD for a couple of years. I'm glad I started on the hard tail as it made me really pay attention to the trail and using my body to control the bike over the rough spots.

However....the dual suspension is great! Climbing and descents over rough and rocky, rooty trails is noticeably easier. Weight-wise the bikes are about the same, but that required investing in better, lighter components which increased the difference in price between the two bikes considerably. I had pretty limited choices regarding size and did go for the WSD to get a bike with decent standover for my short legs.

I love my new bike!!!

Good luck on finding the one that's right for you.
