Was wondering if i already hav an XXC but it seems to not flatten stones as quickly as it used to. if switching to Atoma 140 wud be better choice or just stick to DMT. I hav an ATOMA 1.2k with base. Was considering just getting the Atoma 140 pad and sticking it to the other side of the 1.2k base. Can anyone give a comparison and wud just sticking the pad on the other side of the base work? How does the pad stick to the base, is there adhesive on the pad already or do i need to glue/epoxy it on. If i go that route i will seal the pad to the base with silicone like i did to the 1.2k so i do not get rusting etc in the gaps on the edges. Thanks
