  We present a fix to the overdamping problem found by Laibe & Price (2012)
when simulating strongly coupled dust-gas mixtures using two different sets of
particles using smoothed particle hydrodynamics. Our solution is to compute the
drag at the barycentre between gas and dust particle pairs when computing the
drag force by reconstructing the velocity field, similar to the procedure in
Godunov-type solvers. This fixes the overdamping problem at negligible
computational cost, but with additional memory required to store velocity
derivatives. We employ slope limiters to avoid spurious oscillations at shocks,
finding the van Leer Monotonized Central limiter most effective.
