Bruce I dont know! I'm not good with technicalities.
Maybe the Defense can have flat front of bases and the offense rounded or visevirsa.(sp) Im thinking if the flat hits a round it will cause it to fall. MAYBE! Just dreaming. I would love a base to just go straight.
OR do what I want.
I would like to try and put a small magnet on the inside front of the base but have the offense - and the deffense +. So when they came close to each othe the negative reaction would cause one to fall. I dont know. Im just dreaming.
