Premier trainer for Field Trials? Hunt Tests? Most are busy training. It would be difficult to get them to answer a question about a puppy unless your are a potential client.
To find a quality puppy look for quality parents. Health clearances ( hips, elbows, eyes, EIC clear or carrier are ok, and CNM clear or carrier are ok). For me minimum AFC sire with dam at least SH with Qual placements or JAMs. FT dogs are behind probably 95% of HT dogs , have to be birdy and trainable to get there.
As far as brown dogs go ( I have all black) you might look up a mutt called Ammo, FC/AFC, CFC/CAFC Wings Over An Answered Prayer. Many good chocolates out there.
