“Agreed. Way too technical for novice casters.Who really cares about such nuances?”

As I mentionedoriginaly, for the novice doesn't matter if the answer is 80mph or 40mph, Ijust want to know the correct answer.
Many students bend the wrist too far back like throwing a baseball or football,and then throw their arm far forward to put more energy into the 'cast' and really get the line out there. As weknow, the object is to use less energy and let the rod do the work. Once Ipoint out the line (because it follows the rod tip) moves at about 53mph, they understand that enoughenergy is imparted to the line with an clean, tight movement and there isplenty of velocity to launch the line without the extra 'here we go!!' effort; and they relax and cast better.
In short; once they understand a 'normal' cast moves the line fast/hard enough,they cast better because the casting movement becomes calmer. They all drive,they understand mph, they get that a smaller simple movement of the arm issufficient. All this IMO.
Thanks Silver Creek for the good info.
