I don't seem to have problems using the wide cloth straps such as the ones from Tamrac or Domke. For me, their width makes them easier on my neck, while the greater bulk compared to a thin leather strap doesn't annoy me. I do have one leather strap though. It's from Luigi and came with one of my Luigi half-cases. It's OK, but I can't say I prefer it to my cloth straps. I do like the anti-slip rubber stripes on the cloth ones!
May the light be with you.
