It will be a while for me as I just switched-over to the ASR Delrins but as I understand it, not only are they using Oil Filled UHMW materials with O-ring seals but their sleeves are HARD nickel plated. And they fit right. The cost might be a bit stiff but it looks like they have corrected an issue with something that will last a long time. I too am anxious for some reports but I think it will be a while.
