I do use the breeding as another piece of a large jigsaw. One critical aspect I find is to never stand still. What was a trend can change over time as with French breds once never having a hope in the national. I take the view that you can't have too much useful info. Sorting the wheat from the chaff can be the difficult bit.
The two main reasons I use this forum are to learn new things and to clarify my thinking on things, so stuff like this is always enlightening.
