What's the best way to lower my truck?

My truck is a 1991 single cab I want to go as low as possible with 18s. I want the best ride possible and money isn't an issue. Should I go with the belltech drop kit or with spindles and a cut coil? Blocks and shocks in the back or should I go with the lowering leafs?

I'm pretty new to lowering trucks but I know what each one is and how it works but I just havent seen a definitive answer to the question I'm asking and most of the information I've found hasn't been on our trucks. If there is another way that I'm not thinking of please let me know. Also if your truck is static and you have pictures post them with the setup if possible.

Thanks in advance
