The HR is a great knife. But for me, there really is no reason to bring the HR when you could take the S5. The extra reach for chopping is noticable and the extra length for baton work is also very clear. Also, for me, I like to fillet some fish that I catch and in times past, there simply is not enough blade on the HR to do this quickly with ease. While I have yet to try this with the S5, I can see how it will greatly outperform in this area as well.

Don't get me wrong, the HR is a powerhouse for its size/weight and a great hunting blade. Just for me, the S5 is SO much better in so many areas for a very little weight penality that it is the clear winner for a backpacking blade (for me).
