I'm using a Wacom graphics tablet and i'm trying to use the brush tool in Illustrator CS6 to write some 'curly' text for a project. It all looks fine when i'm drawing but as soon as i 'release' the pen from the tablet the paths seem to snap to something completely different to what I've drawn. See my screen shots below:

This is what it looks like as i'm drawing with the brush tool (before i release the pen):

And then as soon as i take my pen off the tablet the path automatically snaps and looks completely different to what i want:

I have tried playing around with all the settings ie. smoothness & fidelity etc but i cant seem to get the result i want?!?! Is there a setting i need to adjust so when i take my pen off the tablet it doesn't change so drastically?

Any help on this will be greatly appreciated! Thanks.
