I know alot of people on this forum seem to like the FHF bino harness... However I am still using my crooked horn harness and pouch but am anticipating the release of the KUIU harness... If you do a search you should get some good info on this topic.
Nimrod Packs bino harness and removable top cover works for me. Most of the time I don't use the top cover unless the weather is nasty. Their harness can also be used with a detachable pistol holster (I've never owned one).
While I no longer use a Nimrod pack, I have a collection of their pouches of various sizes that attach to belts, packs and shoulder straps. Hands down the best accessory pouches made. Silent, simple one-hand opening and closing.
Used the nimrod system for the past couple years with really no negatives. This year decided to give the FHF harness a try and so far I am really liking it.
Cant go wrong with either in my opinion.
Did not really care for the Sitka, Badlands or horn hunter set ups.
