I'm in the middle of my 10s on my second full HST cycle, and so far so good, except for one thing.  I'm never sore after a workout.  I know that the standard recipe to deal with this is to inccrease volume, but I'm already doing 3 sets of each exercise in the 10s, going to 4 sets each would make the workout drag to almost 90 mins.  I suspect going to 6 days a week would fix me right  up, but I really don't have the time for that, and I thnk it would lead to horrible burnout in me.
Any hints?
