You should try setting it higher... like 100 to 5000 or so.  This means 
that more force is required to break the bonds, so it won't all break at 
once.  Then to tweak, change the glue impulse half life, (or whatever 
it's called) to be larger, meaning that the accumulated force decays 
over a longer period of time, meaning the accumulated force builds up 
more quickly.  You should then find that the impacts build up and parts 
break off as it rolls.
