Contemplating a Losi 8ight, any thoughts.

[miniGranis]

I am thinking about converting a 8ight and I have found a roller.
(Finding a suitable roller isnt that easy in Sweden, this one will set me back about 300 USD)
I would really appreciate it if someone could have a look and let me know what you think.

The buggy is the Race version and was bought new before summer 2008 and have been raced.
All bearings are new and also ackerman (whatever that is...) there is also a alu servo saver.

The plan is to use a 8XL (or 9XL) on 4S and MM.
I hope the 8XL will be better off in an 8ight then in my Revo (tends to run hot).
I might also have a Medusa 36-60-2000 to choose from but that is currently planned for my Revo.
All help/ideas are welcome.
