Does anyone know how channels really work? Some say they are a hinderance and some say they are great???

Does anyone know how channels really work? Some say they are a hinderance > and some say they are great??? …they focus water faster down the board.pros=good acceleration with good holding factors,also loosens the board up somewhat.Cons=much weaker bottom,loads of ding repair in the channels,more time to shape,glass,sand,(don’t over sand!).Channels work best in waves with meat,and a line-up like a point break,slower short beach breaks are not the #1 choice for a channel board.If the channels are built wrong it can make the board spinnyoutty…abit,Herb.
