Dont have any first hand experience of his offspring, but he is a fabulous looking stallion and I nearly bred one of my mares to him a few years ago. Would need a mare with a good dose of blood for eventing but he himself is meant to have a very good temperament
Owned by top Irish Sportshorse Stud - Morningside Stud.
http://www.morningside-stud.com/ The stud is the brainchild of Tom Reed who has done exceptionally well for himself, his stallions are doing well in Holland.
Perhaps you could contact the eventing riders who have Condios progeny to get their opinions about Condios. In the UK Jason Hobbes has a very good 6-y-o called Stilo Kontiko and Michael Diamantides has a very good 5-yo called XLNT Fast and Furioso.
In Ireland Katie O'Sullivan has a good 5-y-o named Loughnavatta Papillon that just started eventing a few months ago and is doing very well.
None of these progeny has TB up close.
Condios is 57% TB by pedigree. If I were to try to breed an upper-level or international eventer I'd follow volatis' advice and put him to a mare with TB up close.
You could also take a look at Conspiracy M2S (approx 52% TB) on our homepage. He is a 5-y-o son of Condios out of a Holsteiner mare named Corniola that, liked Condios, jumped internationally. We bred a test crop by Conspiracy when he was 3 and he produced some super athletes. We recently sold 50% of two of these colts (they are yearlings) to a US junior international eventing rider. Both of these colts will make super athletes. One is out of a 94% TB national hunt mare and the other is out of a Mytens xx x Voltaire mare.
Finally, out of small crops (Condios' sport career came first until I retired him from international sport at the end of 2005) Condios had the 2006 National Champion 4-y-o showjumper, the 2006 Future Event Horse League Vice-champion, and the 2006 Balmoral (Northern Ireland) Champion Showjumper. In 2007 he was represented by 5 horses at the National Championship. The riders like the rideability and athleticism of his progeny.
