Heh. I thought it was just me that had that problem :-) (trying to
squeeze 5.1lbs in to a 4.995lbs bag :-)

I was just concidering this same point this morning. I think the trick
is to try out several variations before you layout the pcb and keep the
utiltization under 70%...

I often have to fiddle endlessly to get some designs to fit (and use the
correct pins).

(I generally pick xilinx parts which have a 2x size with the same pinout
just in case)
