I am not sure if this question has been answered before but if it has I am sorry. I want to get some good flex in the back and I am curious which of these two setups is the best. Either the echobit sissor shackle flip or the ord shackle flip with revolver shackles. They both do the same thing but does anybody have recomendations on which would better serve my k5. /forums/images/graemlins/ears.gif
