Right direction?

[Mad Viking]

I just want some confirmation that I'm heading the right direction for lowering my 71' C20 with leaf springs. First of all, I use the truck all the time for towing and hauling dirt/gravel/wood etc so I want to have the full 3/4 ton capacity. So, this is what I was planning, I have a set of 2.5" drop spindles for the from from POL to drop the front. This will keep the front geometry the same. In the rear I have a set of Hedwig air over leaf helper bags. I am going to remove some of the leafs from each pack to help lower the rear. I will inflate the bags when I tow or haul heavy items. I was also planning on putting in a c-notch and doing an axle flip. This should accomplish my goal of getting about a 3/5 drop with the ability of being able to lower it to a 4/6 by replacing the front springs. Does this sound like it's the right way to do this or am I going about this the wrong way?
