Well said FFF
There is a chance that if you always fly fixed gear and use the BUMPFICHH you will 'forget' to do the appropriate thing when you fly something in which you actually need to do something.
I think this is less likely than forgetting something by using a different mnemonic every time you fly something different.
I certainly find it good to use the same thing and just cross it off as a non action when I go along the list.
Final check I use is reds/blues/greens.
Works for me.
