I have two kits, one with an 18" bass drum and another with a 22" bass drum. The 18" kit I have used to played jazz, rock and klezmer. The 22" kit I used to play jazz and rock. In the past I had one kit with two bass drums, a 20" and a 22" bass drums and used that kit to play a variety of music, including country, rock, pop, jazz and an off broadway play.
I can tune the 18" or the 22" bass drum to have an acceptable sound for any music. I had trouble at first trying to get a combination of bounce and sound from the 18" bass drum. The 18" is easier to carry around and put in a small compact car.
