Ok I see. So an alignment would take a while with some patience. No more eccentric then? Hotchkis UCAs relocate the rear pivot, so you certainly lose the eccentric there. I suppose you could use a cam bolt on the front if you wanted to.

One season of Autox they are all shot I'm am now trying to eliminate as much as I can not a fan of them. Tie rods upper control arms are shot. There are quite a variety of different grades of rod end out there, not all are created equal.

Is the full adjustment feature of the screw in ends an advantage or disadvantage?
I think it is a disadvantage personally. How do you know where to set them without lots of analysis and testing? It takes a lot of time and wrenching to adjust, test and adjust again. There are more variables then the usual caster/camber adjustment. How about brake anti dive? Weight may be a consideration also.
I would rather buy a UCA with engineered and tested geometry with strength where needed for safety but no extra weight. In my opinion, yes it is an advantage, now how much of one, I can't really say. I do know the GTS I'm running comes with very precise instructions that tell you how to set up the hiems in the control arms for a starting point. The GTS has an adjustable track width, so you can move the control arms in a little bit or outwards. So that plays with the hiem joints. 90% or more of the alignment is done with the cam/eccentric bolts just like factory uppers. You set up the GTS per the instructions and have the hiems adjusted so the centerline of the upper and lower ball joints is at the specified angle, took maybe 5 minutes total. I had mine installed and tape measure aligned in under an hour, which is good enough till on the rack. I do know you can dial in more caster with adjustable hiems. as for weight, the uppers that come with the Gerst are actually a tad lighter than factory ones, even with the heims. so any weight savings of a fixed hiem/bushing control arm is going to be very minimal if any. Also, as far as the Gerst is concerned, the uppers are designed and engineered for correct geometry, they aren't just a piece of tubing bent in to a shape. I know Gerst designed his to correct excessive caster and have them actually gain camber. I know I'm comparing the Gerst a lot here but it's what I have currently. I also know that the Hotchkiss setup that a lot on here rave on run heims on their adjustable control arms as well. Same with the Alterkation. I think it's bergman that is making an adjustable upper control arm that runs bushings instead of hiems. I think it is also set up to adjust without removing the cam bolts. So to wrap up, yes I think it is an advantage over a fixed design for the fact that you can tune the suspension more. Once it's set, the fine tuning of the factory eccentric bolts is what is going to be used the most. Weight differences are minimal if any.

The high end johnny joints don't last either, about 5K and they are bad/worn out

Well my wife's daily driver eats the plastic/delrin bushings on her 2" Johnny joints, I should have stayed with rubber bushings...
