I have an Anglo-Trakehner mare. She is by Pennant out of a TB. I am looking to produce a jumper or eventer. Here’s a description of my mare: upright shoulder, short and flat humerus, very upright pasterns, small feet, proportional neck, well defined withers, long back, deep girth, hindquarters could be structurally bigger and carry more muscle, legs are correct. She has a good bit of knee action, moderate impulsion, gaits are not very elastic. She used to event (up to Training), has done some lower level hunters (up to 3’), and is a nice jumper (brave, careful, good form). As far as temperament, she is full of energy, but capable of focusing and putting that energy to work, honest, intelligent, can be spooky (with everything but the jumps). She is not a beginners horse, but a competant intermediate rider can handle her just fine. I honestly like her temperament, and I get along with and in general enjoy riding the “hotter” more sensitive (but obviously still rideable) horses. This foal would be for me. Stallion must be a Trakehner (and I’m not afraid of more TB blood). She is a maiden mare, and as such I would prefer fresh/cooled. However, I might consider frozen. Thank You
Not sure he will tick all your boxes, but this guy has just arrived in the U.S. - http://www.americantrakehner.com/Stallions/Buddenbrock.asp . There have been several recent threads about him, so you may want to run a search to learn more.
Another one that may interest you is Titulus. http://www.americantrakehner.com/Stallions/titulus.asp
Tatendrang is a nifty young Trak stallion - http://www.americantrakehner.com/Stallions/Tatendrang.asp .
And of course, Windfall - http://www.americantrakehner.com/Stallions/Windfall.asp .
I’m sure the Trakehner aficionados on this forum can provide more suggestions.
From what you describe in your mare, are you sure you want to be breeding her ? My advice would be to save your money and buy a young prospect, as it will be cheaper in the long run, and your chances of actually getting what you want will be greater. There are lots of very nice, young, eventing bred Trakehners out there for sale at reasonable prices.
Just so you know, I am not prejuduced against Pennant, as I had his mother for a couple of years, and I also owned his full sister whom I adored.
Tate is probably a good choice as acottingim who owns him also owns one,( if not 2?) Pennant x TB mares who have been bred to Tate so you’ll get a good idea of what you might get.
I hesitated to resurrect an older thread, but my colt out of my Pennant/TB mare was just born on 4/20. Thanks to those that mentioned Tate - I don’t typically “pimp him out” on threads and am only doing so now since I have almost exactly the cross that the OP was talking about. My mare is Pennant’s Valentine - she is by Pennant and is out of a TB mare (Milagro’s Megan by Medaile d"or/Secretariat). And Fiona - I only have the one Pennant mare 
I did keep one of her previous fillies though that is what you are probably thinking of.
Here is the photo of my resulting colt from breeding her to Tate: http://i203.photobucket.com/albums/aa264/acottongim/9daysold.jpg He is 9 days old in the photo (not a great picutre of mom… sorry).
Tate is consistently producing excellent shoulders, top lines, and very good hips. Legs/feet are good. He produces his type consistently. Movement on all foals is very good - canter/gallop is the best gait (he puts his big, ground covering, up hill canter on the foals). Temperment of foals have been smart, quick to learn and friendly. Foals tend to be leggy. Now all of that being said - this is his 3rd foal crop hitting the ground this year and none are started under saddle (Tate is only 6 this year). This particular cross is what I expected it to be, he is leggy (he will be tall), with 3 very very good gaits, very athletic with all of the normal attributes that Tate brings to the table. I plan on repeating the cross as it is a good nick for her.
We have experience breeding first and second generation Windfalls out of thoroughbred mares. Our best foals from that line are from mares such as I’m reading you describe - long, lanky, long pasterns; for us he’s been a “compacting” influence; not trying to generalize, just reporting our results.
We’ve bred (2nd generation, by a Windfall son) one similar combination 4 years in a row and we LOVE the product. For breeding your own, we’ve also found this combination to be extremely vigorous at birth (always up before the mare), strong suck reflex, and so people oriented that we have to be careful NOT to imprint the foal too strongly as they’ll leave the mare to interact with people. These crosses have a very strong personality, as does Windfall, but they’re always positive and FUN!
