It's been a while since I looked in those drum files...

Shots and Holds usually have several variations that are randomly chosen each time you hit Play. If you have not already tried it, generate the songs a few times and see if you can get a sound you like. If lucky, freeze the drum track. Try a Shot as well as a Hold and see what happens.

I'm not sure about the 2 bar endings but they may have variations also. Try the same thing there.
