Don't adjust the height but do adjust the grip and where the pull ends up at. Sometimes pull into the gut. Sometimes to the chest, etc. Also use a curl grip approach, when seems to affect the back in a different way. But again, I do think the stretch can be almost as important as the actual pull to the body when wanting to build muscle size.
To me the one arm pull has certain advantages over the 2 hand pull. Even in most other exercises. Like; one arm overhead presses, rows, lateral raises, etc. If into sports, try one arm DB benches. Sport training centers have different machines, cables, devices,etc to focus on one side or the other of the body.Wanting to insure equal strength and balance to opposing sides of the body. One arm Dl's and one legged squats/step ups can be an excellent movement for BB'ing of strength. And of course sports. Good Luck.
