Yeah, you’ll have complete control, but the compromise is that you’ll need to design your own Tweet/Retweet graphic or write some CSS.
If it’s just going to be the same text over and over that you want people to Tweet you might want a Retweet button instead:
Retweet
So, just create the text and Tweet it on your Twitter profile then extract the Tweet ID from it (by right-clicking on the Tweet date and copying the ID or following the link and copying out the ID) and replace 142828511663620097 with your own.
If what you want is different you could still just apply my custom CSS to your button/link:
Tweet
See demo of the button here:

I can also help you write up some different CSS if you like. The button I’ve designed so far is pretty plain Jane, how I like it. But, I’ll probably write an article on how to utilize CSS3 for feature rich buttons, gradient, shadow, inset text etc.
