5" lowering leaf

[71 GMCDRVR]

I am looking for the best way to lower my 71, it is a leaf spring rear and was wondering what you guy's thought. My question is this, should I go with a mono leaf, a set of 5" lowering leaf springs, or just do the flip to under the axle ????...............I know that the flip will be the cheapest but am curious what you guy's think. Has anybody used the lowering leaf springs and if so how did you like them?? Thanks in advance for your time compadres as usual its always a pleasure
