Not wishing to steal anyone's thunder I train with 2 other fanciers and we have few losses from 30 miles. That may be down to luck but I think it's more related to work done en route. On an annual basis I lose fewer birds training than I do flying at home. One of mine was found this week about a mile from home half eaten it had not been trained. For me I'll do whatever gives best returns and will continue to monitor the situation. However, good luck to fanciers who are prepared to try new tactics.
