I was lucky and had both a MR Nice 7500 and a kifaru Bikini Frame with a Duplex timberline 1 bag at my disposal before I made the big leap( I owned eberlestocks and Badlands before that) and the kifaru is hands down more comfortable and just as durable ( made from the same 500d cordura) as the MR. Better load lifters let you stand upright and a better waist belt take the load almost completely off your shoulders. Also their customer service is probably the best in the business, which it need to be because fitting them can be a little tricky and takes some time. Currently own a Duplex frame with a EMR II and love it.
