hi, i am gonna buy some shock upgraded for my blaster and i was gonna get a set of banshee fronts and possibly a banshee back or a 400ex back. does the banshee back fit directly and is it a good upgrade if anyone has tried it. also the 400ex shock i know needs some fitment adjustments but if anyone has used it please let me know wat you did to make it fit and is it worth it to do it or is there another shock better to use with less work or equal work thanks.
