2 hounds?

We have a 65lb TWC. Everyday we take him on a walk, and he basically follows his nose 90% of the time. He stays on the sidewalk (mostly), but pulls to sniff where he wants, so we generally let him. It takes a little muscle to keep him on track sometimes, but its totally manageable. However. I found another TWC we're interested in adopting - in the 75lb range. I can only imagine he'll act similarly on walks. I'm not sure I would handle daily walks for the both, since it would be tough to fit in a second morning walk if they have to go separately. Am I crazy in thinking I'd be able to walk 2 hounds with a combined body weight that is basically the same as mine? Does anyone have 2 hounds and are able to walk them together without being dragged behind?
