Forgot to post in here. My wife got me the Peak Design Slide for Christmas. After our month long trip to the UK, we both agreed that the factory strap on the D750 is bloody horrible. The Peak Design Slide is amazing. Highly recommended!

I've yet to meet a decent factory strap. They're little more than coarse bragging rights in many cases. I've been using an optech neoprene for a few years now - really dissipates the weight.
