I haven't bought or worn a hat in a long time. what's the difference and what's better?

I'm looking for a new hat. I've been wearing a 9twenty for 4 years now, and I'm trying to change it up.

I have a rather large and bulbous head. My concern is that a straight up 59fifty might be too boxy, making my already large head look even larger. My gf said the 39thirty looked good, but I wasn't digging the elastic band. Also, I'm probably subconciously wanting a genuine hat the guys wear on the field. (Sure, I'm a 30 year old man, but who cares that I want the hat my heroes wear? "I'm wearing the same hat the Phils players wear!" Idgaf if that makes me sound like a child, lol.)

So, is the low profile essentially the 39thirty minus the elastic band? And for style, do you think the low profile will look better on an egghead than the og 59fifty? I wish I could try on a bended and broken in 59fifty, but I don't know anyone who has one. The guy at lids did let me bend one, but it'll take some time to actually get the shape on it.

P.S. Go Phils.

I’m thinking about buying my first Low Profile 59fifty and I had a few questions. I mostly buy the 39thirty, but the hat I want isn’t available in that style and I’d hate to shell out $40-$50 for a hat and not like it.

1. I measured my head and I’m right on the button for a size. Does this style of hat run true to size, or should I expect it to run a bit big or small and order up or down accordingly?

2. The bill is curved, but not as much as the bill of a 39thirty. Is it possible to permanently curve it a bit more?

3. A bit of internet/YouTube research told me that the Low Profile 59fifty and the 39thirty were similar when it comes to crown height and width of hat. Is this accurate?

Thanks in advance for the help.

EDIT: I live in the middle of nowhere. It would probably be cheaper to just reorder a hat if the first one doesn’t fit than to drive several hours to a store that sells New Era hats to try one on.
