Throw anny vs hyzer for uphill? Huh, that doesn't make sense, throw the same shot just throw it higher and more to the left or the right. Shot type is irrelevant for throwing uphill, just alter your trajectory.
A general rule of thumb is to aim your trajectory to the top of the hill and a few feet further right or left and throw a longer disc. If you would throw buzz 300 flat, then get to a 330 uphill shot, throw a teebird or something faster to "club up."
