I have a few friends that sent their cue to McDermott- for re wrap -refinish- and the New McDermott shafts- they definitely have less deflection- turnaround was great. They also offer a lifetime tip replacement on Morri-the high end tips!!!! mark
You will get a much stiffer shaft with the OB calssic then the i shaft.
The OB classic was designed specifically to be stiff.
Try one out before you buy it.
i just got an i2 and also have had an ob classic for awhile. i like the classic better...it is stiffer more solid. the i2 is a little too whippy for my taste and has a lighter, hollowish hit. if low deflection is something you desire, the classic has lower deflection...the i2 is only slightly lower deflection than a regular shaft. also the classic is heavier (which i like in a shaft) around 4oz....the i2's are fairly light, around 3-3.5oz.
