You could do something like this:
Hook: postbit_display_complete

PHP Code:

if ($this->post->userinfo['styleid']=='x') {
$stylename = 'y';
} else {
$stylename = 'z';
} 


Then in your postbit template add:

Style: $stylename

If you want to add more styleid's just change the php code to:

PHP Code:

if ($this->post->userinfo['styleid']=='x') {
$stylename = 'y';
} elseif ($this->post->userinfo['styleid']=='a') {
$stylename = 'b';
} else {
$stylename = 'z';
} 


To add more styleid's keep adding [high]else if[/high] statements

The above should work
