Do you mean that the dough is too elastic and snaps back, or tears easily? I find it very easy to stretch doughs in the 58% to 62% hydration range, with no such issues, if that's what you mean. Either you've just gotten used to working with a high hydration rate, or there's something pretty different between the flours we use...or at least that's all I can figure.
There is NO possible way, I could make a 60% hydration pizza dough with my Super Keynote. I'm not sure I could stretch it without it ripping. And not ripping because it's weak... but ripping because you'd have to have the forearms of Arnold in his prime to stetch it. It's SOOOO hard to describe. I've used Ardent Mills AP, I've used Ardent Mills Keynote. I've used Ardent Mills Pizza flour. But the Super Keynote is a beast. And the only way to get it so it's easy to stretch is to hydrate it. With oil, I'm at 68% right now. And that is actually down... I WAS at 70% but the last month or so, the flour appears to be more wet and I've read online that others are having the same issues with this years' wheat crops.
You may ask, if it's so hard to work with, why do you use it?? Because it makes the best crust. By far. Puffy, light, chewy, soft....
Here is an example... I will admit, this guy got a little carried away on the left hand side

But what that comes out of the oven, you can HEAR the crunch, but inside the crust it's almost strings because it's so soft. I cannot say enough good things about this flour.
