This invention relates to novel compositions comprising anionic block copolymers of {HEAD ~ mono alkenyl arenes} and conjugated dienes where one of the blocks is a controlled distribution copolymer of a conjugated diene and mono alkenyl arene having a specific arrangement of the monomers in the copolymer block, and tailored softening modifiers have a particular structure that results in a surprising improvement in {TAIL ~ properties} for the composition
