TLP shows very small variation with tree height, with sun leaves/higher leaves having a bit more negative values (say 0.5 MPa lower) —see new Marechaux et al paper in J Ecol. I think leaf shrinkage would have some plasticity, because it tends to relate to the elastic modulus (see Scoffoni et al. 2014 Plant Phys paper about leaf shrinkage), and elastic modulus is somewhat higher for sun than shade leaves (Sack et al. 2003 PCE)
