Persimmon standard was 11 degrees for most manufacturers. More important than the loft in my opinion would be the flex pattern of the shaft. My numbers are not dissimilar from those noted. I use a 9.5 degree loft, but my shaft is a Fubuki which I find to be tip soft. The combo was the best I found for distance and accuracy. Awful lot of testing and comparison must go on before you can find a driver anymore. Used to look at persimmon, if the grain looked good, you would stick a dynamic stiff shaft in and go play. Every now and then you found a head, because of the grain and weight, would hit it twenty yards past everything else, that was the keeper you slept with. Miss it, awful hard to get excited about a driver you will replace in six months when something new comes along.
Oh, Dodger.
I took my Wood Bros. persimmon driver to our high school team's practice Monday. As the seniors arrived (early release from school)they wondered what the heck I had. They had honestly never seen one before.
Two young men teachers that help with the girls' team arrived and drooled over it. They hadn't seen a persimmon head for 20 years.
I handed it to one of the seniors and he could not believe how little the head was. I teed the ball for him (he would have teed it way too high) and asked him to swing. He left it way right and could not believe how heavy it was. I suggested he move it slightly forward in his stance. Right on the sweetspot and he roped it about 15 ft. high with a slight draw. He couldn't wipe the smile off his face.
He spent Monday night calling his grandfather's friends looking for a persimmon driver.
