Straight, thin hair...

I have straight, thin hair with gray mixed in and more pronounced on the sides and the middle of the front. I have what I call a Vampire hair line (not sure of what it is really called) but goes to a point in the front middle. I also have a rounded face. I have tried several styles, tried to part on left and then right side and even the middle and just can not seem to get a look that looks good on me. I have also tried hair tonic and gel to no avail.

Any thoughts on what to try? I am looking for something that is not to hard to maintain but will part some effort into if it pays off.
