Although the design of the ISO-T drivers was intended to create more penetrating ball flights with lower spin, I’m not sure you need to go up an entire degree. Very difficult to say without you trying. You really would have to hit them to know for sure. We do not have a “demo” program at this time. Also, we do not have any 11.5 degree in stock yet. Hoping to get some soon. The difficultly in doing a remote demo program is the shaft part of the equation. We can not custom build demos in every loft for players wanting to test. We could possibly have demos in different flexes, but they would have to be in a stock length with a stock brand of shaft. I think that would still be beneficial even though the demo’s wold most likely not have “your” shaft in them. I will see if we can come up with some kind of program.
Thanks for being a fan. We greatly appreciate the support.
