Typefaces

I wanted to see what typefaces may work with in the design and help me get an idea of the different forms/shapes I could use. 

I like the curve on the 6 of the Ayuthaya reg and Lucida Sans Unicode reg. However I also like the bold typefaces like Impact and Charcoal CY as the thickness is really punchy and eye catching. 

I'm not sure if the serifs are best for this but I'll try it anyway just to be sure. I want the 4 to be even on all sides so typefaces like Britannic bold and Palatino will not work. However I think Consolas, Helvetica and Andale Mono could lend themselves well.
