Counter balancing or Swing Weighting? Both have their fans. But if you add weight then both add to the clubs TOTAL weight. If you have a feather in your hand its hard to control. CB or SW are methods to change the feel of the club. Either way can work.
Hit up www.iseekgolf.com and go to the Clubfitting section and you will see an intro to SW and CB story there. I have MOI in production too which is another way of fitting for feel.
