If I was getting a second bike it wouldn't be another one of what i already have.
Go for a different experience, and although a black Speedmaster is the fastest of the Speedmaster/BA family, it's still essentially the same bike.
Go for the 'Bird storm or a RIII Roadster if you want to stay with Triumph.
And, being an unapologetic chromophobe, I really like the murdered out look.
