I'm looking to go the other way. I'm wanting to breed my Arabian mare to a WB. I looked at Pablito. They never responded to my email, however. The breeding manager from Iron Springs Farm did reply that two of their stallions have bred Arab mares. Has any looked at their stallions?
I raised a foal by Pablito out of an Irish Draught x TB mare I used to own (raised the foal for the people I sold her to). The mare had a foal for me by a Selle Francais stallion, so I was able to personally view her produce by two extremely different stallions. The Pablito foal was VERY refined, especially coming from the (coarseish) mare. From what that one turned out like, I'd say he would cross very well with an arabian, probably adding bone and substance, along with a great loin/hip and canter. If my own arabian mare was bigger then her 13.3, Pablito is one I'd seriously consider for her, but his size is just too much for me to be comfortable with for her.
As for him being a jumper sire, well, my opinion is that most arabian mares are lacking in the walk and canter quality. A jumper HAS to have a GREAT canter, one with impulsion and "jump". I would rather breed to a stallion who can produce that quality of "jump" then one who is strictly dressage, because you have no doubts about the quality of the canter coming through. If you research the Hannoverian breeding programs, they frequently add a jumper bred stallion into the gene pool for thier dressage horses, to insure the quality of canter stays where it needs to be. And also, personally, I prefer to produce an "all around" type who can do both dressage and jump...so the jump factor is a deal breaker in stallion selection for my mares.
Edgar is wonderful to work with, his contracts are straightforward and there's no nonsense when dealing with this stallion owner. The foal's owners were so pleased with the whole breeding experience, which is huge for them being first timers to that.
Hope this helps!
