Do keep in mind that my list was designed to do 1 thing. Keep the energy where the band can end the gig with sufficient energy.

If it works I generally wouldn't mess with it. Its always your chose to do whatever I guess.

Why would you end the 9 song gig on a low? The purpose of low is to get people's energy up so they can spend it at the high songs. Always end your gigs on a high energy song.

I tend to do HHLHHLHHLHHLHHH

I usually just do H,M,H,M,H,M,H,L,H,M,H,M. It's simple and never goes too high or low. The only exception is at the very beginning when your songs are weak you put the L a little farther back because it takes longer to get to the bottom end.

on the 12 song I do HHH,L,M,H,MM,H,MM,H with only 1 low song in a normal set, I keep like 2 extra low energies incase attitudes switch
