8850 Upgrade

Just got a cable for my 8850.
And I am wondering... what should I do?

Upgrade to the latest firmware (v5.31)?
Install one of the custom firmwares (i.e MADos or Notix)?
Do a 8850 to 8855 conversion (is this possible)?
Something else?

Can anyone tell me the disadvantages/advantages of these? Or what would be the best to do?

I want to make this phone last as long as possible, because it looks so damn good. Much better than anything I can find these days.

Just have a read on the forums and have a bit of a play with flashing... you'll get the hang of it... no harm trying... you can flash a phone more than once :P
