What this really comes down to is that you want an undrilled fork and pretty paint. Those were your two main qualifiers in your original post. You also mentioned how you wanted NJS but your reasons for that were for undrilled and paint. At that point you realized you could get some gas pipe piece of **** from Jorge for the price of painting a frame so why not?

If your only concern is looks then go for the Sparton. But be warned, when you show up at a ride no one that knows anything about bikes will be fooled one bit by your sparton frame. The reason NJS frames were so coveted a few years ago was because of build quality. Anyone riding one can tell you the same and when they see your sparton frame you might as well have stuck with your Hour.
