Change or Stand Pat?

I currently have a Fuji Norcom 2.5. I’m thinking about buying a Premier Tactical. Would this be a worthwhile investment, or will I not see much of an improvement?

The Premier might be a small jump faster, but it would be a massive jump in the total package. You get a more advanced bike, fast wheels, Di2, and great integrated storage. The net is that it probably would be a lot faster when you factor everything and if your Fuji is totally stock.
