seems to me you're covering a huge range of bikes for a fairly specific type of terrain. With front shocks you can go down a hill at 15mph that you might not want to go down at 10mph and with a lockout you have little penalty on hard roads and uphill. Folks like Asana Cycles who travel light and are probably pretty athletic off road can tolerate bouncy stuff with technique but if you aren't of like disposition front shocks will go a long way for making the ride pleasant and under control.
