I have used a MSD 2 step in conjunction with the MSD soft touch. I also used the soft touch with the dedenbear 2 step. the only difference between the MSD and the Dedenbear was that the Dedenbear was adjustable from 2200 on the low side to 11000 on the high side ..I still have the dedenbear 2step and have lent it out to a couple of guys that run stock and foot brake when they want to mess with the starting line chip
