as a pumpkinpal2 rule, cross everything with everything, and then wince as you cull them! that way, you have covered all the bases; it is not like choosing a state to vacation in and yer stuck with it. or something. bad example.
so, 1058 X 1058,735. 735 X 735, 1058. pretty limited, but you'll have lots of new friends around October wanting seeds! good growing------eric
