Strap Help!!

Hi guys,

I have an em10 ii with the 9-18, 25, and 40-150 f4-5.6.

I am trying to choose a strap to use with it for long hours when my neck gets tired from the neck strap, but I would like the ability to use the strep around my neck. I am looking at:

Joey Ultrafit Sling

Custom SLR Air Strap

Black Rapid Metro

Peak Design SlideLITE

I am having a hard time choosing, can anyone help?

Thanks
