Basketball: Jersey Help!

Alright... I gotta question for ya'll. I went to the mall today to find me a Peja jersey. To my disappointment, every single store was sold out of it.
I decided to order one on-line when I saw I could custom make my jersey. I can't decide between my nickname (Dirk) or my Last name (Spellman) for the name on the back of the Jersey.

Dirk #16
Spellman #16
I'm gonna keep Peja's number, but which jersey do you think is better?

One other thing... Sportztawk isn't letting me upload for some reason... Can one of you guys help me with my avatar? Click here: Kings
In the Official store of the Sacramento Kings thing, there is a logo of their team. I wanted this in my avatar, but ST isn't letting me upload it after I edit it. Can someone edit it for me to where I can upload it? Just the logo... Thanks Alot!

Go with your last name on the jersey. That's what's usually on the back of jerseys.

Here Giants put this in ya Avatar box on your profile..I think this is what you meant by the logo.

I'd stick with your last name, man.

I would keep your last name also.
