I am considering switching from a Jarbidge to a New River for the additional width.
Selected the Jarbidge over the New River because of weight, price, 3 season use, packing size and I don't have an issue keeping feet warm.
The Jarbidge works great when properly adjusted, I did add triangle thingies. I will be able to useit most of the year and add a pad for winter as needed. Was concerned the New River would be too warm during the summer.
My only issue has been the UQ slips off my left shoulder when moving around in the Wbbb.
Will probably try some dutchware first as I am not missing the extra length (I use the footbox in a mummy bag unzipped as a TQ to keep feet warm).
The dutchware will likely solve the issue but I am very reluctant to modify a stock wbbb in any way.
