You're both right (sortof). You're talking about different moment arms!

I believe what sky captain meant is that with a forward COG there is a long(er) moment arm between the COP and the COG, so the stick force is higher to keep everything in balance (the length of the empenage not generally being variable).

Back to my original post, while it's *possible* for there to be download on the tail, in the general, conventional, non-canard civilian aeroplane, it's pretty much guaranteed that there will be an upload. Yes, the aeroplane COP is behind the main wing COP, but the COG's rarely allowed that close that it really matters.
