I have used and am using Devol bushes on hard chrome pins since they were first offered. I bought a set from John Worrall and I believe Bill Beck was contacted to insure I use the clearance that He had instructed MMC to use. I recently took the suspension apart and inspected the bushes and kingpins. The bushes seemed ok but the chrome was wearing thru in the high wear areas. I flipped the KP 180 degrees and put it back together with fresh grease. This was the same situation I found the Vesconite bushes and chrome KP's in. I think I have mentioned that I am suspicious that the plastic bush is picking up and holding grit which wears the KP. I use grease seals. But think I will go back to gaiters.
I see no reason to not try other products. Cost is not the problem. Easy availability is.
