Wouldn’t most of the GRP’s have welsh section B’s in their history not the cob as you would need something to decrease the height more significantly when crossed with a warmblood?
In general yes, the Downland lines (section B) and a couple of the Cusop lines were more popular for the breeding of GRPs; however, there are at least 3 welsh cobs (section D) that I personally know of that were approved, registered and branded GRPs that were imported to this country. My mare, Cosmo, is by one of them.
Especially knowing the quality I could purchase close to home at a different price point just because they are not by a stallion known to the dressage world (stallion has top cob bloodlines so no I am not comparing a “backyard breeder” to the ones I have seen listed…)
OK I"m going to be blunt here. Quality depends on multiple factors when we’re talking about a Welsh Cob. Bloodlines do matter imo but there isn’t just one quality Welsh Cob stallion out there producing dressage talented get. Last year for All-Breed Awards Susan Stepney, Gallod Stud, was the most/best represented breeder in the ranks. She has stood three stallions over the years and all three have had get make it into the All-Breed Awards. I’ve owned a few of hers and I’m well known for not having to second mortgage my home to attain my stock. There are at least 4 other Welsh Cob stallions who come to mind who have produced stock in recent years (decade) that have done well in dressage circles and in the not too distant past Madoc Farms (TX) was putting a lot of cobs out there that were holding their own in dressage and eventing. Many of these animals could be had for $5000 or less when they were young prospects. Some of the prices you’re seeing do reflect training; but it’s obvious that some are spinning what they can. I say this because I’ve had a few personal contacts from the owner of one top stallion who has tried to dictate what pricing I should be listing mine at.
In addition to bloodlines there is type, conformation and disposition to be considered too that all make up quality. I’ve been at this a couple of decades (or more) and I know what recipe works for me. I’m willing to bet that some of ‘that which could be had’ near you for lesser prices have quality…they just need some polish so they can shine; but, it’s hard to say for sure without knowing whose breeding program you are referring to. All I know is that I have found talent in many a Welsh Cob. Whether or not that could easily be seen by others really depended on how hard my arse worked at not limiting it.
