We are working on a second driver, but it will most likely be 2020. The ISO-T should be available by late spring.
The MPF graphite shafts and the Graftech are great shafts. They are manufactured by the largest composite manufacturer in the world, the same that makes other “brands” you would be familiar with, but I am not at liberty to disclose. We test and test and test do not bring to market anything that we do not feel performs well. I believe our shafts are excellent performers and a great value.
As far as drivers go, it is important to understand that ALL premium drivers that are sold (TaylorMade, Ping, Callaway, Cobra, Maltby…) are manufactured to perform up the USGA limit. The USGA has performance guidelines that must be met to be considered conforming and all the premium drivers will be designed to perform right up to that limit. So, from a ball speed off the face standpoint, they are all the same. That does not mean that you might find one that performs better for you. One may have a better shaft head combination for you than another. You may like the looks of one over another and that can effect the way it performs for you. One may have adjustability that has adjustments that dial into to your game better. So, you might find aspects of one brand or model that work better for you, but the science of ball speed off the face and the guidelines we all have to work under as set by the USGA prevent any separation in performance off the face among the premium brands.
