Rollerblade Inline Skates I Am Training For A Rollerblade Marathon. I Have Some Quick Questions On Skates?

I am training for a Rollerblade Marathon. I have some quick questions on skates? - rollerblade inline skates

1. Swiss bearings are the best stock?
2. What are the pros and cons of running style in-line skates.
3. How much of a disadvantage, I would be if I buy on plates of regular physical activity, and after some time, replacing them with new wheels and new Swiss camp. They come with wheels and SG9 bearings 90mm to start. 90II by Rollerblade Crossfire.
