I don't how much detail Ed went into in his discription of the Arri kit,,,,,but, it is indeed a completely different mold than the old Monogram kit,,,the Monogram kit is a re-release of the Aurora kit, and the Arii kit is a release of the Otaki molding
the Arii/Otaki kit is felt by many to be a better detailed kit than even the Tamiya 1/350 kit, I traded the one I had for 1/700 ships a while back,,,,in a move to save some space on the finished shelves
if you have the Arii/Otaki, or can find one,,,,you will have the best Enterprise model in any scale,,,and while you are searching for it, try to find the add on aircraft set,,,,,,also, if you can find one, the Detail & Scale Enterprise book is a big help for detail photos, and has reviews in the back comparing the kits
