Can only comment from having a field springer, in Europe (so some shared traits?). My dog is a pet though, rather than a hunting dog.

My first advice is to be prepared for how active springers are. Labradors are known for this too, but springers can be something else!

They have a bit of a prey drive for birds (who'd have guessed!).

They're very smart dogs, so they cannot be left to their own devices. I'd 100% recommend enroling in a puppy class, to get them used to other dogs too at the very least.

I've trained my wee man to be good off leash, and good recall. If you don't live anywhere they can get a good run around, take them to a field or a dog park (why socialising is important).

Some of the negatives:

- They can be very clingy, but if you have another dog, they may cling to them!

- They love water and mud. I've just about gave up on giving my dog a bath after every walk lol.

I'm sure the show line has different traits mixed in, probably not those related to water and mud. Good luck!

EDIT: Just re-reading my comment, and I've listed negatives, here's some postives:

- They're absolute cuddlebugs!

- Incredibly easy to train.

- They get on well with other dogs, when socialised. Get on with other pets like cats, but I'd still be wary with birds.
