Convert 7 Speed to 8 Speed?

[Stefan Mikes]

That is pretty much the way I use it, and its not so bad, just being a bit OCD about the gear spacing LOL.

Well, my Vado SL has a 10-speed freehub based drivetrain, and I was mad with big gaps between the gears I use the most. With the freehub body, it was easy to replace the cassette with one evenly spaced but having no granny gear. After I decided that cassette deserved replacing due to wear, I re-used the stock one. And switched my OCD off.
