I would think that if you're just starting out MTN biking that a hardtail would be a good start, just to get your skill-level up. After you've outgrown your hardtail and feel as though you still want to be into MTN biking ( I'm certain that you will), then your next move up would be the FS.
Personally, I feel that it's a progression in terms of skill-level development:
Rigid Hardtail ---> Hardtail ---> FS
Starting with a Hardtail is good, but I personally wouldn't suggest starting with a FS.
But I digress..
These would be my personal suggestions:
Jamis Dakar XC Comp (26) ~ $1700 *(FS)
Jamis Dragon 29 Sport ~ $1350
Jamis Exile 29 Comp ~ $1100
- Slim
PS.
IDK...I just think you'll better appreciate a FS after first, riding a HT. You'll know better what to do with it!
