Okay, regarding the use of chains, are they most efficiently used on ME or DE days...or should it/they be 'mixed up' a bit? Perhaps it is the case that they are only to be used exclusively on one of those days, though it may just be such general knowledge that my search isn't turning up an answer to it. Sorry if this is a no-brainer question, but all searched turn up far more detailed answers, with none really addressing whether or not they can be utilized on both days, or which day the "belong". THanks
