Not sure what the Midwest trails are like, but if they are narrow and/or tight, you may want to go with the X. The only benefit of the X is the 64" width on tight trails and the significantly better turning radius. However, the suspension on the X is stiff... I mean really stiff, too stiff in my opinion for slow speed rocky type trails. I own the X and after only a couple hundred miles had had enough and sent off my shocks/springs to Shock Therapy, along with a description of my primary riding style/terrain, and detailed list of all the aftermarket modifications as well as planned modifications. They determined shock valving and spring rates based on the provided information and sent them back ready for me to mount. I haven't been able to really drive the buggy since installing the new setup, but I can already tell it will be much much better than it was for my type of riding. I think the factory setup would be fine for high speed relatively smooth trails, but not for slow speed rough trail riding.
The cost for the Shock Therapy treatment was about $1500 which is no small amount. You can buy the Talon R for only $1000 over the cost of the X and the R sounds like it comes with a much better suspension overall, so my suggestion is that unless you need the narrower width and the tighter turning ability, go with the R.
