you could think of using Grafwenstolz's sire Polarion, grand prix dressage ride of Laura Bechtolsheimer, absolutely FANTASTIC temperament and 3/4 TB but moves like a warmblood. champion Trekhener sire.
definitely Stanhopes Didicoy. Amazing temperament, competed Intermediare dressage, show jumped 1m 30 easily, can be ridden by anyone, a total gent. Plenty of advanced eventers by him too, with a few competed up to 3 star level. good size as well. stands hobgoblins stud
