I am currently building a pickguard for my super strat and I too am using the thrash factor set for a HSH setup and I ended up going with a hot stack in the middle. I HAVE NOT HEARD IT YET, as it is still in construction but I did a great deal of research and came up with this pickup combination to best suit MY preferences. My ideal of a 'balanced' set would be a modern high output bridge and a vintage low output neck and I chose to stick the hot stack in the middle to kind of have the same amount of power as the neck taking into account the difference in string vibration at the two different positions. I'm using a set of triple shot mounting rings and a push push pot for series/parallel operation of the hot stack and seven way switching. Im making this setup to play punk rock. Will let you know more when it is finished and I have played it.
