I think Allen Hopkins made an interesting argument in favor of alternating breaks. He made analogies to other sports. He said imagine a team in football scoring a TD and then receiving the next kick off or a team scores in basketball and gets the ball back (make it take it). I know these are distinctly different sports, but I think he does have a point to a degree
I have heard all the arguments for alternate break and understand them all. None of them outweigh the value of seeing a player get hot and string a big package IMO. Everyone has their own opinion.
The tennis thing I am talking about still allows someone to get loose and put a package together while assuring the other guy will his chance to do the same thing.
