go for the WERM frame with WERM stick, it certainly rocks
fit where your orginal one fits, has a LS switch in the grip frame and you just need to solder 2 wires to the board. Its fully adjustable trigger
ya i would have to agree that the werm stick kicks ass i got one of those on my shcoker but i heard that you can also get an angle frame from ipb that can be put on impy/shockers my friend got one for his impy and it shoots great
