SO if that is the worst, the BEST bet would be to MOVE IN- before the topspin takes over and it climbs above your shoulders. This way you can take it as a volley, or half volley. Another idea is when practicing, have someone hit 50 of them (high kicking backhands) to you while you hold your ground and LEARN to hit a ball ON THE RISE-- ala the Nick Bolleteri - Andre Agassi school of thought.
This is a hard shot for everyone but it becomes easier with practice. So pick one of those 3 styles mentioned above, or practice all three, until you get comfortable handling these difficult shots.
