Lifted 5" in front need help on rear leafs

I have a 2012 pre runner and have a spindle lift up front with a TRD fox coilover that adds another 1 inch on that (5 inch total) I have a 2" block setup in the rear from just the spindle lift, but now I have an inch extra up front. I see 3" 3.5 and 2.75 leaf springs. What do I get?
I was looking at the 3.5 rough country setup. Do you think that 1/2 in the rear extra will be noticeable. I only need 3" total, but those are budget springs

 

At least go with all pro expeditions. 4" lift unloaded. But they are made for weight so stiff unloaded.

 

You don't think the 4" is too tall for what I have and what I had? 4" up front and 2" block in rear was what I had.
Now I have 5" up front and need about 1" in rear wiht the block to level it out.
I want to do away with the block setup

 

So I want to ditch the blocks for sure. The leaf pack I'm looking at is 3.5 inches. I only need 3 inches to level the truck. Do you think the 1/2 inch extra is noticeable?
