Reply to Move/replace buttons?

Hi,

I'm looking forward to getting a MidiFighter when the new batch becomes available. However, I'm not sure what button colours to choose because I'm don't know how I'm going to use it yet (I'm planning to play with a few mappings posted here and evolve from there) so I was believeing of buying a few extra so I can swap them in an out.

Is it easy/sensible to change the buttons regularly? I don't expect it to be difficult but I am concerned it might damage the midifighter board through wear and tear.

Any thoughts?

Cheers

Adrian
