Quiver tips are, relative to the rods which hold them, inexpensive and found in all coarse fishing tackle shops. They can be bought in various test curves, which correspond to how stiff the tip is (often measured in ounces.) The lower the test curve, the less stiff the tip is (i.e. the less weight required to bend the tip.) The test curve of the tip should be carefully considered as it could drastically impact on the bite detection/playing of the fish and should relate to the type of fish targeted and weather conditions.
