Wolf,

I have been using strategy since they first introduced it. I like the fact that it works for horses of any age and exercise group, especially since mine range in age from babies to 30. Also depending on what type of hay you feed(alfalfa/bermuda grass) they have formulated it so your horse gets all the correct vitamins and minerals to complete the hay.
I have been very happy with it, and all of Purina's products. I like how much research goes into the development of their feeds and the quality of the ingredients.

Glad that I could help.
