A2 skitters along on a black Ark for me - like a stone skipping on water. I don't think these are effectively compatible with oilstones though I see you aren't trying to use oilstones.
The Ruler Trick has been suggested. Maybe that will work on A2. I've never used the Trick myself, on anything. Most everything I've read over the years suggests that registering the blade flat is the way to go and indeed I have done so and I get beautiful edges in regular high carbon steel. There's a wonk somewhere who I'm sure would proclaim my edges junk. I'm an old 'if it ain't broke don't fix it' sort of guy from way, way back. Ignorance is bliss I suppose.
I actually thought all of the A2 'celebrations' had died out over the last year or so as people ran into similar problems as yours and if not outright problems had grown tired of the extra time and effort needed to get a good, initial edge. The explanation offered is usually 'user error' (and I see that seems to have happened in your thread too) though that doesn't seem to be valid in your case as you are able to sharpen other steels just fine.
I don't know if a steel is worth changing one's technique and equippage over. I tend to think not, but I too am a hayseed like Mike Tobey.
