Control arms, jionts or bushings or both?

Ok, I'm about to build some new arms and was thinking about using Currie JJ on the lowers and the axle side of the uppers with the factory type bushing on the frame side of the uppers. Is this a bad Idea? Do I need some type of bushings on the lowers or will it be ok with the JJ's down there? I searched so dont go there. Has anyone built short/mid arms like this?

i ran my mid arms w/ re flex joints on the frame end, rubbers on the axle. it doesnt matter which end has which.

our 3 link kits are RE on the frame, rubber on the axle, and small RE's on both ends of the upper

I run RE joints at both ends of my uppers and the axle end of my lowers, with rubber at the frame end of the lowers only. Trackbar is RE at one end and a 7/8 heim at the other end.
