Cindy, This is merely an observation... Chains give the whip the opportunity to adjust the length of the trace at the vehicle/work end. Slot end or roller bolt traces give the opportunity to adjust the length of the trace at the collar or breastplate. Much of this is practicality, some is tradition...along with the statement by one old-timer that a gentleman never drives 6-up. -- noel jones, aago athens, tennessee, usa ------------------------------- frog music press rodgers organ users group www.frogmusic.com _________________________________________________________ To Unsubscribe, change to Digest or Vacation mode go to: http://www.drivingpairs.com/dpmem.html `````````````````````````````````````````````````````````
