the problem with TB/Welsh crosses is that they sometimes end up at undesirable heights. The best selling heights are either 14.2hh or under, or 16hh or over. Anything in between is not "fashionable" at the moment (don't go jumping on my back here - my mare is 15hh.)
Personally I would breed Freckles to a Welsh stud so you can produce a pure foal - let's face it, pure foals sell better. And I honestly think that sellability should be taken into consideration when breeding for a foal - what if (God forbid, but it could happen) something happens and you have to sell it? You want to give the horse the best possible set-up for future.
Moomoo, I will look around for stallions I like and post them :)
ETA: are you up for AI or no? How far are you willing to ship the semen if you are willing to do it? How much are you wanting to spend on a stud fee?
