springs for lowering my 07 taco

ok so im lowering my 07 regular cab tacoma. i have the bilstein shocks on their way for the front. Ill be getting the x2 steel leafs or some 4x4 leafs to bring the back down a bit. plus qa1s to get rid of the stock rear shocks. I plan to get 2" blocks for the back and djm control arms later on. but while i have the the leafs and front and rear shocks installed (which may be on for a while) should i go with the x2 performance drop spring for the front or the srock ride height performance spring also from x2. will the drop spring be too much when i finally put the djm control arms on? whats he smartest way to do this since i will have the truck withput the blocks and control arms for a while. i dont want to buy the drop springs now and then have to buy thw stock height springs when i put on the control arms.in the future. whats the best choice?
