I'm a road rider looking to get a hardtail for some easy mountainbiking with my husband and friends. I'm considering the 2009 Specialized Myka HT Expert and Myka HT Pro. Anyone have experience with either of these bikes? Since I'm still learning about mtb components, are the differences in these two models significant enough to warrant the extra cost of the Pro? I plan to test a few in the near future, but any advice beforehand is welcome!
