I still dont understand the whole thing with the leather and hardware. Can someone please explain these 2 things for me? How many leathers are there? What's the best? What's the second best? Which leather is the most popular? Does it affect price? etc etc etc Also, for the hardware. What's the difference between the hardwares? Whats the best? Most popular? Does it affect the price? Thanks all!!!
