hi in my short experience (4 years), i have never had much luck with latebreds, (after july). probably because i have not trained them properly? im not sure, but think they need plenty of training in there year of birth, and need alot of time spending with them, i end up losing 90% of them by 2nd or 3rd race following year, may just be me, but saying that you might get a gem or 2 out of them, i have a 2007 latebred, that is my best bird by far, bred in late june, and he has won 4 times for me now, including first fed this year. 2 channel races and 2 inland from 85 miles to 390 miles! so if your patient with them, i suppose you may be o.k, good luck
