Callaway Golf Sets

how is the golf club with the lowest trajectory produces more distance?

45 degrees is the perfect angle for the distance, isn't it?

45 degree angle is perfect when there is no wind resistance (which, with a ball rotates, there will always be). The real reason for lower trajectory irons go further is because they are longer clubs. The trajectory touches a little bit, but in reality it is because the club is a little longer. All your irons should be apprx .25 -. 5 inches above the rail above, and your driver should obviously be the longest club in your bag.
