Nice.
You might consider upgrading to Toshi or Kashimax straps. They are 2 layers of leather with a nylon layer in-between. The nylon keeps them from stretching. WELL worth the extra expense if you use toe straps. They last a very long time, too. The ones I've used last 2 seasons of regular training/racing use and I only replace them because they look dirty but they still work fine.
I've found no significant performance difference between single or double strap Toshi use. I'm a bigger (and stronger) than average guy and singles keep me in the pedals. But, I will admit that doubles do feel better.
