Changing the default cursors icons

Hi
I have been trying and trying to change the default cursors icons that are a bit...eh
The procedure I followed is this:

First from settings I made sure that X rather than moksha is selected
then I downloaded a new theme and unpacked it is /usr/share/icons/

Then I symlinked /usr/share/icons/default/index.theme to the index.theme I wanted to use

The cursor changed correctly but at reboot it was the default one again.

I then removed the alternatives symlink from etc/alternatives

Again the cursor worked but at reboot it was gone...

I then tried lxappearance route..no effects whatsoever

it seems I am unable to make the change stick...any suggestion?
