Need opinion on jawbone

[Bucket]

Anyone care to throw out some age estimations on this buck I killed Saturday? Thanks in advance!

I would say 3.5 but I'm new to aging jaw bones

edit. I think 3.5, trying to read up on aging deer using the jaw bone and there is actually some conflicting information.
