New Bushings...greasable or not

[Chevyman63]

I'm going to install new bushings in all my springs and shackle mounts and was wondering what you all think. Is it worth it to go with greasable bushings or will using the standard poly bushings do just fine? My build is going towards a really nice cruiser with some light to moderate wheeling at times. I am going with the DIY4X shackle flip to get rid of my 4" lift blocks and the EZinch for an extra bit of lift to eliminate the saggy butt look. I don't think the greasable bushings are necessary for my build, but since I'm going that far with the shackle flip...?

Thanks in advance for your thoughts.
