Welcome to the brotherhood! Don't worry about your head shape, it will be fine. All heads look good bald. I've never seen a bald guy that didn't wear it well.
You look just fine, Bendub. I don't see any reason for you to be concerned about your head shape. It's been said before, but I'm going to echo it, because it's true: There is no such thing as a perfect shaped/sized head. Your head is unique to you.
You'll never know unless you try. Good luck in your decision.
I for an example am so unique that i would be insulted if one size fits all hat would fit me
O h yea head shape -you are trippin dude it is perfectly head shaped
Natedawg- nice thick beard on your baby

... kidding man

pretty baby you must be proud
Unless your head has been run over by a truck and the reconstructive surgery was not quite a success--there are no "funny head shapes." So, is there a truck interaction in your background? If not, stop fretting.
Welcome to the bald brotherhood Bendub. Give it a try, I agree with all that has been said here, your head is fine and you will look good bald.
