I have replaced my bridge with SD Quarter Pounder. Now I get solid bite in 3 pick up selections, from the centre to the bridge position. My neck pick up has a bluesy sound, so I am not going to change that, neither the middle one. This said, however, my squier is a standard series UK market issue, and costed me a lot, and the pick ups are generaly better. Point is, why don't you change only the bridge pickup first and see what that does for you? And preferably, get someone to carry the pick up from abroad. I got my SD for INR 2500, almost 30% cheaper than what it sells for in India.
