@teamrobot - dialed list except for hub engagement. if you're going from a bottom-of-the-line hub to something nicer, it's noticeable, if you have to pedal for speed or momentum. i'm not saying the upgrade has to be a $500 rear hub, but the difference between a super cheap rear hub found on a $1-$2k bike and a "good" rear hub with better engagement is legit. on budget rear hubs, i've had my foot blow off pedals (flat pedals, not clips) as i upshifted while pedaling on travsery portions of trail. the slack was just too great and the violent thud...
