First off, I'm not doing much baking outside of the realms of pizza, my apologies if this is common knowledge.
So far I've experimented with hydration levels between ~ 58-68 % (depending on the type of flour and pizza style). Based on my observations, it seems that lower levels of hydration produce dough that is easier to work with/stretch into skins with less sticking to the proofing container etc. Higher levels, on the other hand, result in dough with more oven spring and therefore a (subjectively) "better" crust but can be a real pain to work with.
Are these observations accurate? Are there other indicators to watch out for?
Most importantly, which end of the spectrum should I aim for? And how exactly does perfectly hydrated dough look/feel like (this probably varies quite a bit depending on the pizza style)?
