ICON UCA and Total Chaos LCA combo (Specifically how well they hold up in the NE)?

Im wondering who is running Icon Billet Delta Joint UCA and or Total Chaos LCA up here in the NorthEast? If so:

1.) How long have you had them installed on your truck
2.) How often do you clean and lube the Heim joints of the UCAs (where they mount to truck)
3.) How often do you clean and lube the lower ball joint on the Total Chaos LCAs?

If you could do it over you you still purchase?

I have a local shop that is advising against installing these due to what a pain they are to maintain and the high failure rate (joints seizing up, becoming loud/noisy) up here in the NE.

*I currently have a set of TC UCAs on my truck and while they still function great after ten years, they are showing cosmetic wear: powder coat starting to fail. And i really take care of my truck: fresh water rinse, clean and parts lube after every snow storm and consecutive road salting. I also undercoat my truck and suspension parts every year with clean NH Oil.

Thanks for the help!
