Hi,

I encountered a similar problem with Civil with 
rotational sprites. The anti-aliasing artifacts 
that blend down to the transparent background 
colour would show up rather badly on the 
playfield when the sprite was rendered. 

The answer is fairly simple: get your artists to 
remove the anti-aliasing artifacts around the 
edges of the sprite. 

You can use an alpha, but this is more coding 
work for what amnounts to a very simple bit of 
faffing around in the GIMP/PhotoShop. 

It's annoying to learn the lesson after you've 
produced a load of artwork, but once bitten...
