Tough call but I think you're in a pretty similar situation as I have been in before.
Given your team... Which is very solid... I would normally say screw the rookies and go for it. But with you keeping 15 (like I do in my league) I think that gives you the flexibility to add and hold onto a guy like Galy. The options are good but not amazing.
