A tip from Louis Armbruster. I bought a couple of the hard ones for two new longbow shooters. They came round , open and stiff. Louis's tip worked, it was soaking them with Neat oil from the inside until it showed through. Then set them out in a hot sun, blow drier, or anything to get them hot. Then work them until they collapse, then put on an old shirt, and wear them rather tight for an afternoon with only a couple of arrows in them. The quiver will mold to your body shape. After the Neats oil completely dries then I use the Pitch Blend on the outside. They both will will get the job done, but I find that it is easier to get the neats oil more places faster, especially when treating them from the inside out. Another tip I got from Louis Armbruster. If you are walking fast and hard enough that you can hear your arrows in your back quiver, you are not hunting, you are hiking. Once you get one completely broken in and shaped to fit your body, they become an old friend that you cannot do without and your freedom of movement will be rewarded with silence and still have the ability to get that second arrow out of the quiver and onto the string in short order. Perhaps, I am the only one that occasionally needs to get that second arrow out of the quiver and onto the string, but it pays off in bowhunting for me, more often than I care to think about, but it always pays off.
