I don't think the drop in WE is enough to make you reconsider it. It's not that big of a drop, plus 25 is a pretty low WE anyways. Keep it on him if you really want the extra year. Also, I have noticed that if you tell a kid in recruiting that you are going to RS him, if he accepts it (in DII and DI) that means he's probably not good enough to play at your school anyways!
