You can ride any DFW region trail on a hardtail, but full suspension is nice. If tuned right, it works well for keeping your rear tire planted on the rocky/rooty little climbs we have scattered around. If you frequent loop 'D' at Isle du Bois, or the red loop at Johnson Unit (both on Ray Roberts), FS is nice to have for the rocks there. To be honest, the only place I feel I "need" a FS is going off a drop on the east side of FWMBA's Gateway trail. It's something like 6 foot I think. Personally, I prefer FS, but I spend time riding bike parks outside of the state, so I get good use out of it.
My opinion, if you do go FS and stay in DFW, definitely lean toward an XC or milder trail bike. No need for an enduro. My daily ride bike is a 140/140 mm and I usually lock down the rear shock riding in DFW (it's not a 100% lock, but close). It leans a little more toward enduro than XC, and I am a little slower than others on some of our more XC climbing kinda stuff... if that matters (doesn't to me
)
