Got to compare them beside my 5X25X56 P4 S&B and while not the same, it is almost to close to call from inside the store, one thing is sure those are worth the price, took arrangement to have 2 kept until the Mtl show and no taxes sale, end of Feb.... one 2.5X10X50 and one 3X12X56, i will decide then wich one i will take, chances are big, i will take both, story to follow...
