As an owner for decades of various Specialized mtb's, I'd say stick to what you want. Steel hardtail will work, even a full rigid will still be fine. Most of my bikes are steel rigid mtb's and I still take them on trails once in awhile. They work for me. Although I also do enjoy my 2011 Hardrock Disc, aluminum and all, there's no replacement for steel to me.
Just do your homework, take your time and don't rush buying. @
mechanicmatt- thanks for linking my bike.
