Before revision:  For  fair assessment of tail dependence and stability of  estimation under small sample size, we support the use of tail dependence measures weighted over all angles compared with maximal and minimal ones .
After revision:  For fair assessment of tail dependence and stability of estimation under small sample size, we support the use of tail dependence measures weighted over all angles are suggested, with tail Spearman's rho and tail Gini's gamma being interesting novel special cases of TCMs .
