And since you're considering a 26-30T big cog anyway, I don't think a long-cage RD would be so bad at shifting. (If you wanted to do a triple plus a corncob, then I'd probably try to make a "road" RD work.)
Then why make short cage mtb derailleurs? Deore, XT, XTR, etc
Also, how do you mean about the B screw adjustment?
