I bought my last mountain bike in 1993 (front suspension Trek 9800). I think it might be time for a new bike.
Last experience I had with full suspension bikes was back in the early 90s when I worked in a shop and sold the Trek TC3 bikes (some of you may remember the stack of doughnuts suspension). That thing had uncontrolled rebound and enough rear end sway to make you seasick. I haven't ridden any other FS design.
Can anyone point me to a primer on the FS designs currently available, and maybe make a recommendation or two on which would be best for cross country riding? I particularly care about reasonably light weight and directional stability (meaning no sloppy forks or rear ends). Edit to add that I weigh about 200 lbs.
