I have a JBL woody sawed off mag with three 9/16" bands. I would like to upgrade the bands. I was thinking either a bit thicker or a little shorter. However I currently have 3 9/16" bands on there (stock) and I think that if I went to 5/8" I could only do two. Would this still increase my power? or am i better off keeping the three 9/16" bands and just getting some a little shorter. i was thinking 17" bands. What do you guys think?
