I think you can change your typesh/shot special for 10 DTs. I'm not 100% sure about this, since i never did it, but i've heard about it before. That way probably is faster and cheaper for you.
You can change this go to saith I know he might do it for even less then 10 dts. I'm not certain but I know he won't even charge 10 dts for a special change typically.
