I will second what pussuskattus suggested...although it is definitely more work/time, we found that it was very worthwhile to mock up the drawers and try out our handles that way. We ordered various sample sizes of our handles and DH cut some scrap wood planks in the lengths of our drawers. We then just placed the handles on each board and it was VERY quick and easy to determine which size to go with. It was surprising what we found...definitely some different outcomes than what we had thought before mocking up. There would be no need to cut wood, though...could easily just use posterboard or scrap cardboard from a shipping box. And the ribbon idea would be easy, too. Would save the step of buying the pulls if you don't know for sure yet what you want. Good idea for next time! Good luck with your search on the vintage pulls!

We have 2 pulls on the cabs that are 30 or wider and 1 pull on everything else. I find that with the smooth operation of our cabs that having 2 pulls is nice. I can reach a pull from either side of the drawer and never use 2 pulls at the same time. It helps if you have a few people in the kitchen at the same time, esp for the 36" wide drawers. I also like the double pull look better on the wide and deep drawers. Most don't do a 4 stack of drawers that wide, so I am not sure how a single pull would work in that instance. These are 30" wide drawers with 2 pulls. I can't picture them with only 1. Notice that neither pull is very far from the center:

Why not check out Lee Valley for stainless bar pulls that come in many sizes. IMO pulls should be in proportion to the cabinet door or drawer. I can’t even see a 5” pull working to open a 40” drawer properly and if you need 2 they look silly.

I have to disagree w/you naysayers. It's quite functional, thank you. it doesn't pull the drawer wonky and works just fine, nice and smooth. Nothing is pulled out of alignment, even if I do use one hand. And yes, my heavy pots are in there. Perhaps your cabinet maker isn't using sturdy drawer glides. good lord. Not all pulls come in 12" and larger. I happen to think the pulls in the other pic posted looks very modern and I didn't want the look of appliances sized pulls on my drawers, in spite of what you think is correct. I think the 3 of you are being a little dramatic. I see double pulls all the time.
