Where - and when - to handle

I've never gotten into making multiple-sectioned pots. I've made a few, but they just seem to take too much energy or something. However, I threw a few two-piece pots yesterday, and today I spent the morning figuring out if handles or lugs would improve their overall shapes. I enjoy this part. I like to make temporary handles and set them on the pot here and there and see how it changes the piece. I decided the vase on the left didn't require anything, and decided to place lugs on the middle vase and then spent close to an hour tinkering with the piece on the right, as shown below: (the last picture is what I decided on.)
