"A GSP will get you more"....substitute "pointing dog" and I've been hearing that all my life...and "sometimes" its even true......the 'real truth" in this statement depends on the hunter, the dog, and the "field".....every flushing dog owner has stories about the pointy dog guys leaving a field sneering at their flushers and saying..."we got em all"....only to kill the first of several birds within site of the Pointy Dog blowhards as they put their dogs up...AND VICE VERSA.......
I saw this a lot first hand this past season in Montana.....there with a single Lab and staying in campgrounds that was mostly populated with "pointy dog" people who smirked at the single Lab as they walked along their staked out "chain gangs" of multiple pointers.....I can tell you it didn't bother me one bit to clean double daily limits of Sharptail on the tailgate right in front of them, while they walked by on various "tasks" stopping to either say...."you killed those with THAT dog" and "we couldn't find em today WHERE WERE YOU".......
In the end its a personal thing and you really should spend a lot of time with someone that has the breed you think you want......and then weigh that against what you hunt the most, and where you hunt those species......its been said already but New York is a "cold place"....if you duck hunt most of the time and Upland Hunt in New York, (pretty much makes it a Grouse/WoodCock thing), I'd be looking at a flusher......if you travel to hunt and will spend multiple days a year in areas with Prairie Birds and wide open vista's and only duck hunt once in a while then "maybe" the Pointy Dog makes more sense......
Either one can do both and each group will tell you that "his choice" does them both better even while admitting that there are "shortcomings".......pick the one that bests suits what you hunt the most and the habitat that you hunt them in........
I got no skin in the German Dog thing....seen a few hunt and some of those were very good......some weren't.....be aware of the "prey drive" that oftens gets them in trouble when Cats are around....
The male/female choice is personal....I saw as many 600 yard female Setters in Montana last season as I saw males that ranged that far.....for what its worth I've always had males, (labs), but my next Lab, and my first Setter, will both be females....part of that is the desire to have a bit smaller dog, part is curiosity, and the rest, and tis is a big part, is the wife is convinced a female is "easier" than a male.....we'll see on that one....my luck I'll get a 30 lb female that thinks she's King Kong, considers "close" to be 900 yards and the only thing she likes more than hunting is beatin up boy dogs.....
Good luck on your choice.......
