Axtell 5S cam

What is known about this cam. I am thinking of a 2S cam from RGM, but found this one. Any thoughts, concerns.

I have a copy of the Axtel 5S in my race bike. It makes good power but it's not great for idling.
I know it has identical lobes for the inlet and exhaust and I'm pretty sure that that lobe is the same ( or near enough) as one of the lobes on a 4S.
I didn't notice much difference when I swapped the 4S for the 5S.

Somewhere on the net there is a page with the specs of most Norton cams.

Found the page on cam specs:
